$Id: CHANGES,v 1.1 2009/01/20 00:28:14 sdhsdh Exp $

11/01/2006	Release 1.0.

10/09/2006	Perform a static/dynamic code audit; plug some minor
		bugs (see CVS changelogs for more information) and
		perform minor clean-up.

08/07/2006	Implement MAX_INITIAL_RTR_ADVERT_INTERVAL handling,
		patch from Yoshifuji Hideaki / USAGI.

05/23/2006	Unblock SIGALRM signals at startup.  Some scripts/programs
		seem to run radvd from ALRM-blocked context which breaks
		the timers.

05/23/2006	Redefined IgnoreIfMissing: by default, radvd will now
		try to reinitialize failed interfaces automatically.
		IgnoreIfMissing is still needed if radvd is started when the
		interface isn't up, and it also quenches some messages
		relating to missing interfaces.

03/29/2006	Implement RDNSS draft, using non-allocated
		IANA ND type value 25, by Lauréline Provost,
                Mickaël Guérin, Adrien Clerc, Gaetan Eleouet,
                Bahattin Demirplak, Lionel Guilmin (at the
                ENSEEIHT, Toulouse)

03/06/2006	Fix the default STDERR+syslog logging methods, so
		we don't try to unnecessarily log to STDERR after
		forking.

01/18/2006	radvd-0.9.1 did not initialize AdvDefaultLifetime (etc.)
		appropriately, unbreak the "clean-up".

01/13/2006	Release 0.9.1.

12/30/2005	Great cleanup of signed/unsigned values, add
		-Wall and a number of other warnings to CFLAGS
		by default.  Do not allow signed values for
		HomeAgentPreference anymore.

12/30/2005	Fix a couple of  IPv6 Ready Logo Phase-2 IPv6 Core
		Protocols Self Test issues, patches from Yoshifuji
		Hideaki / USAGI.

11/13/2005	Create a short FAQ in README file.

10/28/2005	Get interface MTU automatically, so that you can
		use jumboframes and advertise MTU >1500.

10/19/2005	Release 0.9.

10/18/2005	Transfer sole maintainership of radvd to Pekka Savola.

10/18/2005	Make the radvd.conf syntax dump default
		in radvdump and remove the previous default to
		reduce code duplication.

09/28/2005	Add NEMO Basic support (RFC3961) and fix default
		HomeAgentLifetime, from Ville Nuorvala.

08/18/2005	Implement more robust timer handler, especially
		because some Linux kernels don't seem to behave
		all that well; see http://lkml.org/lkml/2005/4/29/163.
		Based on extensive testing & reports by
		Tomasz Grobelny.  NB: the bug report was caused by
		a bad timer patch in PLD's kernel package, and this
		should not occur often with standard kernels.

07/24/2005	Implement a new logging method "stderr_syslog" which is
		now also the default.  Everything is logged on syslog,
		while the most important messages (i.e., start-up failures)
		are also logged on stderr.

07/08/2005	Release 0.8.

07/05/2005	Change the more-specific route ND option code
		from de-facto '9' to the official '24'.  Change
		back in defaults.h if you need old behaviour.

07/05/2005	Fix wrongly calculated prefix with Base6to4Interface
                on ppc and maybe other big endian arches, from
		Debian #301543 by Sam Hathaway.

07/05/2005	Fix Linux-2.6.12-bk4+ error with HUP signal,
		from YOSHIFUJI Hideaki / USAGI.

03/29/2005	Merge a part of MIPv6/non-MIPv6 code, make printing
		error messages nicer.

03/22/2005	Be a bit more informative about config file parsing
		errors.

02/21/2005	Release 0.7.3.

02/19/2005	Fix crash when reloading config with AdvSendAdvert off.

02/15/2005	Merge a few fixes and improvements from USAGI:
		 - support microsecond scheduling and fix RA intervals
		 - send zero router lifetime when forwarding is disabled
		 - use a more flexible inter-RA delay

01/07/2005	Accomodate interface indexes > 9999, from Hagen Fritsch.

12/15/2004	Advertise zero Router Lifetime when shutting down;
		implements a SHOULD in RFC2461 section 6.2.5.

10/16/2004	Update Mobile IPv6 to match RFC 3775, from Greg Daley.

08/20/2004	Minor documentation cleanups.

03/09/2004      Implement "IgnoreIfMissing" interface flag, which can be
                used on interfaces which aren't enabled when radvd starts
                but will later become available (e.g., Bluetooth) --
                and then you wish to send HUP to radvd to activate the
                configs.

02/21/2004      Further cleanups, to fix autoconf/autoheader problems
                with newer toolchain; mostly by Marko Myllynen.

02/20/2004      Clean up a bit: remove old junk from configure.in,
                rename "log()" to "flog()" to satisfy newer GCCs,
                allow underscores in the interface names (the last two
                fixes already committed earlier).

01/19/2004      Make radvd check for forwarding status using procfs on
                Linux; needed with 2.6 kernels.  Loosely based on
                a patch by USAGI.

11/21/2003	Add support for Router Preferences and More Specific
		Routes from Markku Savela <msa at burp.tkv.asdf.org>.
		NOTE! The specification is not final yet, there will be
		changes!  (Man page, documentation and radvdump support
		by Pekka Savola.)

09/11/2003	When starting up, check if the MAC address is all zero
		(could happen e.g. with bridge interfaces with no attached
		physical interfaces), and warn if so. For more information,
		http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=103469

06/10/2003	When chrooting, check the possible return code 
		from chdir("/").

03/08/2003	Add patch from MAEDA Naoaki <maeda.naoaki at jp.fujitsu.com>
		to discard RS's from the unspecied source address with
		link-layer address option, as required by RFC2461.

10/28/2002	Release 0.7.2:
		 - add support for VLANs (from USAGI)
		 - make it compile better on newer NetBSD's (NetBSD)
		 - fix a syntax error in radvd.conf(5) sample documentation
		 - use IPV6_RECV{HOPLIMIT,PKTINFO} not 
                       IPV6_{HOPLIMIT,PKTINFO} if supported
		 - (in Red Hat spec file) don't create radvd gid explicitly
		 - a lot of coding style cleanups

01/16/2002	Release 0.7.1.

01/12/2002	Update config.{guess,sub} from ftp.gnu.org; update INTRO.
		Marko Myllynen and Debian bug #115992.

01/02/2002	Ensure NULL-termination with strncpy.

12/31/2001	Radvdump fixes: eliminate a warning of Prefix Information
		sections with '-d -f'; add a note that
		{Min,Max}RtrAdvInterval cannot be obtained with '-f';
		implement '-e' to be used with '-f' which omits all
		advertised default settings. Mostly by Marko Myllynen.

12/28/2001	Small cleanups.  AdvSendAdvert is implicitly off by
		default.  Check configuration file permissions; must
		not be writable by others, and if non-root,
		not by self/own group.  By Marko Myllynen.

12/21/2001	Check via sysctl that IPv6 forwarding is enabled;
		exit unless debugging is enabled.  Triggered by
		Marko Myllynen.

11/22/2001	MinRtrAdvInterval for MIPv6 is 0.05 seconds, not 0.5.
		(Note: untested).

11/20/2001	Rework BSD device memory management a bit, minor cleanups.
		Version bumped to 0.7.0.

11/14/2001	Maintainership of radvd transferred from Lars Fenneberg
		to Pekka Savola and Nathan Lutchansky.  Lars' CVS
		repository adopted, and changes merged from the -pX
		branch.

08/29/2001	Minor change for NetBSD 1.5.1 compatibility.
		(Nathan Lutchansky)

07/20/2001	Support for non-multicast links, like ISATAP.
		(Nathan Lutchansky)

07/03/2001	Minimum MTU has been changed to 1280 in the latest RFC's.
		(Pekka Savola)

06/30/2001	Check for possible buffer overflows; replace strcpy with
		strncpy.  No fatals found.  Remove redunant radvd -t check.
		(Pekka Savola)

06/24/2001	Fix 1-byte overflow in /proc/net/igmp6 handling,
                clean out possible memory garbage when sending RA's
		(patch from <yoshfuji at linux-ipv6.org>).

06/19/2001	When dropping root, also set up supplementary groups
		properly.  On Linux, when sending RA's, check that the
		interface has joined all-routers multicast group.  Add a few
		RFC2461 MUST sanity checks when receiving datagrams.  Clean
		out non-EUI64 addressing scheme and other minor bits.
		(Pekka Savola)

04/28/2001	Misc cleanup and bugfixes, automake support.

03/28/2001	Grammar cleanup. Integrated 6to4 support through
		"Base6to4Interface" option in prefix configuration. Signal
		handling fixed by blocking on select() rather than recvmsg()
		so SIGTERM/HUP take effect immediately now. (Nathan Lutchansky)

03/27/2001	Security fixes: close stdin/out and chdir("/") via
		daemon() to prevent possible exploits, and a flag to allow
		radvd to set[ug]id to an unprivileged user (from Pekka Savola).

02/01/2001	scope_id is not supported in glibc2.1. So it is now
		compiled conditionally.

01/31/2001	Add CC variable to Makefile. Fix bug with IPV6_ADD_MEMBERSHIP
		handling. Set scope_id when sending packets.

12/02/2000	man pages update, rewritten pid file handling, rewritten
		signal handling (SIGHUP and SIGTERM), gcc warnings cleanup,
		new radvdump option -f: print received RAs in config file
		format (by Marko)

11/19/2000	integrated the last two change entries into the main source
		(patches by Marko Myllynen), fixed bug in log.c, fixed file
		description leak in readin_config, rewrote code in timer.c,
		updated man pages again (from Marko Myllynen, too), PID
		file support (patch from Marko Myllynen, based on a patch
		from Tommi.Komulainen at iki.fi)

15/08/2000	RFC 2461 updates, Mobile IPv6 extensions added

14/07/2000 	added RA interval option and modified some default values
		for timers

06/15/99	changed to run with glibc 2.1 on RedHat 6.0.

10/23/97	radvd will now accept any prefix length in its config
		file but will warn about unusual ones

10/19/97	removed backwards compatibility code in recv.c.
		IPV6_HOPLIMIT support is now assumed to exist.

10/16/97	the Makefile install target now uses mkinstalldirs.

10/16/97	changed all u_int*_t to uint*_t for better POSIX
		compliance and portability. Needs 2.1.57-CVS or glibc.
		BSD seems to need patches.

10/16/97	more intelligent configure; tries to figure out
		where the IPv6 libraries and inclues are (if not in
		the standard places). Searches in /usr/inet6 and /usr/ipv6.

10/15/97	integrated small patches for glibc and BSD from Craig and
		Philip

09/14/97	EUI-64 "support"

09/01/97	centralized all includes into includes.h for easier
		maintainance

08/25/97	changed all occurences of IPV6_TXINFO/IPV6_RXINFO

01/19/97	now also the rest of a line followed by a '#' is treated
		as a comment in the config file

01/16/97	added IPPROTO_IPV6/IPV6_HOPLIMIT support, so now incoming
		RS' and RAs are checked if there hoplimit is 255 (on Linux
		this only works with kernel version 2.1.21 and above)

01/15/97	lots of portability cleanups; radvd is now using autoconf

	 	hosts)

11/17/96	added a man page for radvd(8)

11/17/96	some minor filename changes

<h1>RADVD Introduction</h1>

<p>
by <a href="mailto:lf at elemental.net">Lars Fenneberg</a> et al. Updated
2002-01-12.
</p>

<a href="http://www.ietf.org/rfc/rfc2460.txt">IPv6</a> has a lot more
support for autoconfiguration than
<a href="http://www.ietf.org/rfc/rfc791.txt">IPv4</a>. But for this
autoconfiguration to work on the hosts of a network, the routers
of the local network have to run a program which answers the
autoconfiguration requests of the hosts.

On Linux this program is called
<a href="http://v6web.litech.org/radvd/">radvd</a>, which stands for
Router ADVertisement Daemon. This daemon listens to Router Solicitations
(RS) and answers with Router Advertisement (RA). Furthermore unsolicited
RAs are also send from time to time.
<a href="http://www.ietf.org/rfc/rfc2461.txt">RFC 2461</a> defines most
functions of radvd.

Router Advertisements contain information, which is used by hosts to
configure their interfaces. This information includes address prefixes,
the MTU of the link and information about default routers.

Of course the routers can't autoconfigure themselves, so the information
on the routers has to be provided by the administrator of the system.
This is done by manually configuring the interfaces and routes and by
configuring the router advertisement daemon.

<p>
A small and simple configuration file for radvd might look like this:
</p>

<p>
<pre>

interface eth0
{
        AdvSendAdvert on;
        prefix 2001:db8:0:1::/64
        {
                AdvOnLink on;
                AdvAutonomous on;
        };
};

</pre>

It says that radvd should advertise (AdvSendAdvert on) the prefix
2001:db8:0:1:: which has a lenght of 64 on the interface eth0.
Also the prefix is marked as autonomous (AdvAutonomous on) and as on-link
(AdvOnLink on). The both currently default to enabled but are included
here for introductory purposes; it isn't necessary to define them.
All the other options are left on their default values.

Autonomous means that the prefix can be used for automatic address
configuration and on-link means that the hosts can assume that all the hosts
which use this prefix are reachable via the interface on which the host
received this RA.

The prefix must be 64 bits long (apart from very few exceptions), as dictated by
<a href="http://www.ietf.org/rfc/rfc2464.txt">RFC 2464</a> and other
standards for different link-layer technologies. For more
details, see <a href="http://www.ietf.org/rfc/rfc2462.txt">RFC 2462</a>
(IPv6 Stateless Address Autoconfiguration) and
<a href="http://www.ietf.org/rfc/rfc2464.txt">RFC 2464</a>
(Transmission of IPv6 Packets over Ethernet Networks). For more information
on configuring radvd please look at the manual pages which are included in
the radvd distribution.

So, when an interface on a hosts is UPed and a RA is received, the host
can configure an address on the interface by using the prefix and
appending the EUI-64 identifier derived from the hardware address
(also called link-layer token). The EUI-64 identifier is simply appended
after the prefix. For example:

<p>
<pre>

   Announced prefix:    2001:db8:0:1::

   MAC address:         00:07:E9:7B:02:59

   EUI-64 identifier:   0207:e9ff:fe7b:259

   Configured address:  2001:db8:0:1:207:e9ff:fe7b:259

</pre>

The host can also choose a default router by examining the RA.
the rest works automatically.

So now we've configured radvd, but we still need to configure the interfaces
and set the routes (on the router). There's a lot of good material on
setting up IPv6, and the reader is encouraged to have a look
at it; for example:

<p>
<ul>
<li><a href="http://www.bieringer.de/linux/IPv6/IPv6-HOWTO/IPv6-HOWTO.html">http://www.bieringer.de/linux/IPv6/IPv6-HOWTO/IPv6-HOWTO.html</a></li>
<li><a href="http://people.debian.org/~csmall/ipv6/setup.html">http://people.debian.org/~csmall/ipv6/setup.html</a> (for non-Debian too)</li>
</ul>

Installation:
=============

Run configure, e.g.

./configure --prefix=/usr/local --sysconfdir=/etc --mandir=/usr/share/man

See configure --help for additional command line arguments.

Run 'make' and 'make install'.  On BSD, you may need to use 'gmake'.

Configuration:
==============

See INTRO.html, radvd.conf(8) and radvd.conf.example.

Frequently Asked Questions:
===========================

Setting up radvd is very simple, so the most frequently asked
questions have been about what radvd _doesn't_ do...

 1. How do I set up the router running radvd to automatically
    configure an address from the prefix advertised in Route
    Advertisements from upstream?

    -- You don't.  By the specification, routers ignore RAs.
    You'll probably need to use manual configuration.  But you
    can't use the same prefix on two links in any case unless you
    use something like proxy-ND (draft-ietf-ipv6-ndproxy-04.txt).
    You may need to re-think your topology; prefix delegation
    (e.g., manually or with RFC3633) may help.

 2. How do I set up the router running radvd to automatically
    configure the interfaces to use an EUI64-based address?

    -- You don't.  The design philosophy of radvd is that it's
    not the _router's_ configuration tool, but a route advertising
    daemon.  You'll need to set up all the addresses, routes, etc.
    yourself.  These tasks are something that system initscripts
    could possibly do instead.

 3. I have a dynamic /48 prefix.  How do I set up radvd to:
    a) set up interface addresses and routes on downstream
       interfaces, and
    b) advertise /64 prefixes from the /48 on downstream interfaces?

    -- For a), this isn't supported. For b), radvd includes special
    support for 6to4 upstream interface but assumes that the interface
    addresses/routes are set up manually.  This should probably
    be done in the initscripts or manually. (Though if someone were
    to send a patch for b), it might be incorporated.)  

 4. How do I set up radvd to do either unicast or multicast routing?

    -- You don't.  Radvd is not a routing or forwarding daemon.
    You need to set any appropriate routing/forwarding first,
    and then radvd to only advertise the prefixes to hosts as
    appropriate.

$Id: TODO,v 1.1 2009/01/20 00:28:15 sdhsdh Exp $

                       NOTE WELL
                       =========

	*NONE* of the items are being actively worked on.
        So, if you're interested in one of these features,
        it means you'll have to submit a patch... :-)

read list of interfaces with SIOCGIFCONF (AF_INET6 support in the kernel would
be nice) or from /proc

Quoting Peter Bieringer (peter at bieringer.de):
> Das war's schon. Ach ja, wenn Du mal eine neue Version machst, kannst Du
> noch einen Schalter einbauen, damit radvd trotz debug-level >0 auf Wunsch
> als daemon in den Hintergrund starten kann?
[ Peter wants that a debugging level greater than 0 doesn't stop radvd
from forking.]

support for few protocol constants defined in RFC 2461 Sec 10 is missing.

consider whether UnicastOnly flag should be detected by radvdump.

read the man pages one more time and make sure their are understandable
and English is correct

The following parts of RFC2461(bis) are not implemented:
 - section 6.2.1: Adv{Valid,Preferred}Lifetime that decrements in real time,
   that is, one that will result in a Lifetime of zero at the specified time in
   the future. (MUST)
 - section 6.2.5: when AdvSendAdvertisements changes to FALSE, we don't send 
   a final RA with zero Router Lifetime (we just send it when shutting down).
   (SHOULD)
 - section 6.2.8: if the link-local address of the router changes, it should
   multicast a few RAs from the old address with zero router lifetime, and a
   few from the new address. (SHOULD).

Consider whether to support RFC 4286 (Multicast Router Discovery).

Consider whether to support multiple IPv4 addresses with Base6to4Interface
(currently the code just uses the first one).

Consider whether to support a generalization of Base6to4Interface for
arbitrary IPv6 prefixes, to be used for automatic generation of downstream
prefixes.  Also consider whether this would need to support multiple IPv6
prefixes on the upstream interfaces.  See question 3 in README for more on
this.

Use getifaddrs() instead of ioctl SIOCGIFADDR and other friends.  The
problem with this is that e.g. RHL73's glibc didn't support getifaddrs(),
and before glibc 2.3.3 getifaddrs() didn't use netlink so it didn't work
well with IPv6.  So, some kind of compat library would be needed if this
would be used...

Consider whether radvd should work around missing/broken interfaces by
default, especially if a previously working interface gets disabled.

Implement Secure Neighbor Discovery (RFC 3971).

# This file is a shell script that caches the results of configure
# tests run on this system so they can be shared between configure
# scripts and configure runs.  It is not useful on other systems.
# If it contains results you don't want to keep, you may remove or edit it.
#
# By default, configure uses ./config.cache as the cache file,
# creating it if it does not exist already.  You can give configure
# the --cache-file=FILE option to use a different cache file; that is
# what configure does when it calls configure scripts in
# subdirectories, so they share the cache.
# Giving --cache-file=/dev/null disables caching, for debugging configure.
# config.status only pays attention to the cache file if you give it the
# --recheck option to rerun configure.

##   (We might end up doing this anyway to support other compilers.)

## - Using -M directly means running the compiler twice (even worse

radvd \- router advertisement daemon for IPv6

.BI "[ \-d " debuglevel " ]"
.BI "[ \-C " configfile " ]"
.BI "[ \-p " pidfile " ]"

.SH DESCRIPTION
.B radvd
is the router advertisement daemon for IPv6. It listens to router
solicitations and sends router advertisements as described in
"Neighbor Discovery for IP Version 6 (IPv6)" (RFC 2461).
With these advertisements hosts can automatically configure their
addresses and some other parameters. They also can choose a default
router based on these advertisements.

Note that if debugging is not enabled,
.B radvd
will not start if IPv6 forwarding is disabled.  IPv6 forwarding can be
controlled via sysctl(8),
.B net.ipv6.conf.all.forwarding
on Linux or
.B net.inet6.ip6.forwarding
on BSD.

Similarly, the configuration file must not be writable by others, and if
non-root operation is requested, not even by self/own group.

.SH OPTIONS

For every one character option there is also a long option, which
is listed right next to the "short" option name:

.TP
.BR "\-v" , " \-\-version"
Displays the version of
.I radvd
and then aborts.
.TP
.BR "\-h" , " \-\-help"
Displays a short usage description and then aborts.
.TP
.BR "\-d " debuglevel, " \-\-debug " debuglevel
With this option you turn on debugging information. The debugging level is
an integer in the range from 1 to 5, from  quiet to very verbose. A
debugging level of 0 completely turns off debugging. If a debugging level 
greater than 0 is used,
.I radvd
doesn't background itself on start. The default debugging level is 0.
.TP
.BR "\-C " configfile, " \-\-config " configfile
Specifies an alternate config file. Normally the compiled in default
.I @PATH_RADVD_CONF@
is used.
.TP
.BR "\-p " pidfile, " \-\-pidfile " pidfile
Specifies an alternate pidfile. Normally the compiled in default
.I @PATH_RADVD_PID@
is used.
.TP
.BR "\-m " method, " \-\-logmethod " method
Specifies the logging method to use. Possibly values are:
.RS
.TP
.B none
Completely disables any logging.
.TP
.B logfile
Logs to the logfile which is specified by the
.I \-l
option. If no logfile is specified on the command line, then
a compiled in default is used (see next option).
.TP
.B stderr
Logs to standard error.
.TP
.B stderr_syslog
Logs only the high messages (of at least LOG_ERR priority) to standard
error, and everything to syslog (default method).
.TP
.B syslog
Logs to syslog.
.RE
.PP
.TP
.BR "\-l " logfile, " \-\-logfile " logfile
Specifies the logfile to use when using the logging method
.IR logfile .
The default logfile is
.IR @PATH_RADVD_LOG@ .
.TP
.BR "\-f " facility, " \-\-facility " facility
Specifies the facility (as an integer) when using syslog logging. Default
is @LOG_FACILITY at .
.TP
.BR "\-t " chrootdir, " \-\-chrootdir " chrootdir
If specified, switches to 
.I chrootdir
before doing anything else.  This directory and its
subdirectories must have been populated first.
For security reasons,
.I \-u 
must always be used when using
.IR chrootdir .

Note that on Linux
.I radvd
requires access to the
.I /proc
filesystem,
so it is more challenging to set up the chroot environment.
.TP
.BR "\-u " username, " \-\-username " username
If specified, drops root privileges and changes user ID to
.I username
and group ID to the primary group of
.IR username .
This is recommended for security reasons.
You might also need to use
.I \-p
to point to a file in a
.I username
-writable directory (e.g. /var/run/radvd/radvd.pid).
.SH FILES

.nf
@sbindir@/radvd
@PATH_RADVD_CONF@
@PATH_RADVD_PID@

.TH RADVD.CONF 5 "20 Aug 2004" "radvd @VERSION@" ""
.SH NAME
radvd.conf \- configuration file of the router advertisement daemon
.B radvd
.SH DESCRIPTION
This file describes the information which is included in the router
advertisement (RA) of a specific interface.
.P
The file contains one or more interface definitions of the form:

.nf
.BR "interface " "name " {
	list of interface specific options
	list of prefix definitions
	list of route definitions
	list of RDNSS definitions
.B };
.fi

All the possible interface specific options are detailed below.  Each
option has to be terminated by a semicolon.

Prefix definitions are of the form:

.nf
.BR "prefix " prefix / "length " {
	list of prefix specific options
.B };
.fi

Prefix can be network prefix or the address of the inferface.
The address of interface should be used when using Mobile IPv6
extensions.

All the possible prefix specific options are described below.  Each
option has to be terminated by a semicolon.

Decimal values are allowed only for MinDelayBetweenRAs,
MaxRtrAdvInterval and MinRtrAdvInterval.  Decimal values should
be used only when using Mobile IPv6 extensions.

Route definitions are of the form:

.nf
.BR "route " prefix / "length " {
	list of route specific options
.B };
.fi

The prefix of a route definition should be network prefix; it can be used to
advertise more specific routes to the hosts.

RDNSS (Recursive DNS server) definitions are of the form:

.nf
.BR "RDNSS " "ip [ip] [ip] " {
	list of rdnss specific options
.B };
.fi

.SH INTERFACE SPECIFIC OPTIONS

.TP
.BR IgnoreIfMissing " " on | off

A flag indicating whether or not the interface is ignored
if it does not exist at start-up.  By default, radvd exits.

This is useful for dynamic interfaces which are not active when radvd
starts or which are dynamically disabled and re-enabled during the time
radvd runs.

Current versions of radvd automatically try to re-enable interfaces.

Enabling IgnoreIfMissing also quenches certain warnings in log messages
relating to missing interfaces.

Default: off

.TP
.BR AdvSendAdvert " " on | off

A flag indicating whether or not the router sends
periodic router advertisements and responds to
router solicitations. 

This option no longer has to be specified first, but it
needs to be
.B on
to enable advertisement on this interface.

Default: off

.TP
.BR UnicastOnly " " on | off

Indicates that the interface link type only supports unicast.
This will prevent unsolicited advertisements from being sent, and
will cause solicited advertisements to be unicast to the
soliciting node.  This option is necessary for non-broadcast,
multiple-access links, such as ISATAP.

Default: off

.TP
.BR "MaxRtrAdvInterval " seconds

The maximum time allowed between sending unsolicited multicast
router advertisements from the interface, in seconds.

Must be no less than 4 seconds and no greater than 1800 seconds.

Minimum when using Mobile IPv6 extensions: 0.07.

For values less than 0.2 seconds, 0.02 seconds is added to account for
scheduling granularities as specified in RFC3775.

Default: 600 seconds	

.TP
.BR "MinRtrAdvInterval " seconds

The minimum time allowed between sending unsolicited multicast
router advertisements from the interface, in seconds.

Must be no less than 3 seconds and no greater than 0.75 *
MaxRtrAdvInterval.

Minimum when using Mobile IPv6 extensions: 0.03.

Default: 0.33 * MaxRtrAdvInterval

.TP
.BR "MinDelayBetweenRAs " seconds

The minimum time allowed between sending multicast
router advertisements from the interface, in seconds.

This applies to solicited multicast RAs.
This is defined as the protocol constant MIN_DELAY_BETWEEN_RAS in RFC2461.
MIPv6 redefines this parameter to have a minimum of 0.03 seconds.

Minimum when using Mobile IPv6 extensions: 0.03.

Default: 3 

.TP
.BR AdvManagedFlag " " on | off

When set, hosts use the administered (stateful) protocol for address
autoconfiguration in addition to any addresses autoconfigured using
stateless address autoconfiguration.  The use of this flag is
described in RFC 2462.

Default: off

.TP
.BR AdvOtherConfigFlag " " on | off

When set, hosts use the administered (stateful) protocol for
autoconfiguration of other (non-address) information.  The use of
this flag is described in RFC 2462.

Default: off

.TP
.BR "AdvLinkMTU " integer

The MTU option is used in  router advertisement messages to insure
that all nodes on a link use the same MTU value in those cases where
the link MTU is not well known.

If specified, i.e. not 0, must not be smaller than 1280 and not greater
than the maximum MTU allowed for this link (e.g. ethernet has
a maximum MTU of 1500. See RFC 2464).

Default: 0

.TP
.BR "AdvReachableTime " milliseconds

The time, in milliseconds, that a node assumes a neighbor is
reachable after having received a reachability confirmation.  Used
by the Neighbor Unreachability Detection algorithm (see Section
7.3 of RFC 2461).  A value of zero means unspecified (by this router).

Must be no greater than 3,600,000 milliseconds (1 hour).

Default: 0

.TP
.BR "AdvRetransTimer " milliseconds

The time, in milliseconds, between retransmitted Neighbor
Solicitation messages.  Used by address resolution and the Neighbor
Unreachability Detection algorithm (see Sections 7.2 and 7.3 of RFC 2461).
A value of zero means unspecified (by this router).

Default: 0

.TP
.BR "AdvCurHopLimit " integer

The default value that should be placed in the Hop Count field of
the IP header for outgoing (unicast) IP packets.  The value should
be set to the current diameter of the Internet.  The value zero
means unspecified (by this router).

Default: 64

.TP
.BR "AdvDefaultLifetime " seconds

The lifetime associated with the default router in units of seconds. 
The maximum value corresponds to 18.2 hours.  A lifetime of 0
indicates that the router is not a default router and should not
appear on the default router list.  The router lifetime applies only
to the router's usefulness as a default router; it does not apply to
information contained in other message fields or options.  Options
that need time limits for their information include their own
lifetime fields.

Must be either zero or between MaxRtrAdvInterval and 9000 seconds.

Default: 3 * MaxRtrAdvInterval (Minimum 1 second).

.TP
.BR AdvDefaultPreference " " low | medium | high

The preference associated with the default router, as either "low",
"medium", or "high".

Default: medium

.TP
.BR AdvSourceLLAddress " " on | off

When set, the link-layer address of the outgoing interface is
included in the RA.

Default: on

.TP
.BR AdvHomeAgentFlag " " on | off

When set, indicates that sending router is able to serve as Mobile
IPv6 Home Agent.  When set, minimum limits specified by Mobile IPv6
are used for MinRtrAdvInterval and MaxRtrAdvInterval.

Default: off

.TP
.BR AdvHomeAgentInfo " " on | off

When set, Home Agent Information Option (specified by Mobile IPv6)
is included in Router Advertisements.  AdvHomeAgentFlag must also
be set when using this option.

Default: off

.TP
.BR "HomeAgentLifetime " seconds

The length of time in seconds (relative to the time the packet is
sent) that the router is offering Mobile IPv6 Home Agent services.  
A value 0 must not be used.  The maximum lifetime is 65520 seconds 
(18.2 hours).  This option is ignored, if AdvHomeAgentInfo is not
set.

If both HomeAgentLifetime and HomeAgentPreference are set to their
default values, Home Agent Information Option will not be sent.

Default: AdvDefaultLifetime

.TP
.BR "HomeAgentPreference " integer

The preference for the Home Agent sending this Router Advertisement.  
Values greater than 0 indicate more preferable Home Agent, values
less than 0 indicate less preferable Home Agent.  This option is
ignored, if AdvHomeAgentInfo is not set.

If both HomeAgentLifetime and HomeAgentPreference are set to their
default values, Home Agent Information Option will not be sent.

Default: 0

.TP
.BR AdvMobRtrSupportFlag " " on | off

When set, the Home Agent signals it supports Mobile Router
registrations (specified by NEMO Basic).  AdvHomeAgentInfo must also
be set when using this option.

Default: off

.TP
.BR AdvIntervalOpt " " on | off

When set, Advertisement Interval Option (specified by Mobile IPv6)
is included in Router Advertisements.  When set, minimum limits
specified by Mobile IPv6 are used for MinRtrAdvInterval and
MaxRtrAdvInterval.

The advertisement interval is based on the configured MaxRtrAdvInterval
parameter except where this is less than 200ms.  In this case,
the advertised interval is ( MaxRtrAdvInterval + 20ms ).

Default: off

.SH PREFIX SPECIFIC OPTIONS

.TP
.BR AdvOnLink " " on | off

When set, indicates that this prefix can be used for on-link
determination.  When not set the advertisement makes no statement
about on-link or off-link properties of the prefix.  For instance,
the prefix might be used for address configuration with some of the
addresses belonging to the prefix being on-link and others being
off-link.

Default: on

.TP
.BR AdvAutonomous " " on | off

When set, indicates that this prefix can be used for autonomous
address configuration as specified in RFC 2462.

Default: on

.TP
.BR AdvRouterAddr " " on | off

When set, indicates that the address of interface is sent instead of
network prefix, as is required by Mobile IPv6.  When set, minimum
limits specified by Mobile IPv6 are used for MinRtrAdvInterval and
MaxRtrAdvInterval.

Default: off

.TP
.BR "AdvValidLifetime " seconds "" | infinity

The length of time in seconds (relative to the time the packet is
sent) that the prefix is valid for the purpose of on-link
determination.  The symbolic value
.B infinity
represents infinity (i.e. a value of all one bits (0xffffffff)).
The valid lifetime is also used by RFC 2462.

Default: 2592000 seconds (30 days)

.TP
.BR "AdvPreferredLifetime " seconds "" | infinity

The length of time in seconds (relative to the time the packet is
sent) that addresses generated from the prefix via stateless address
autoconfiguration remain preferred. 
The symbolic value
.B infinity
represents infinity (i.e. a value of all one bits (0xffffffff)).
See RFC 2462.

Default: 604800 seconds (7 days)

.TP
.BR "Base6to4Interface " name 

If this option is specified, this prefix will be combined with the
IPv4 address of interface
.B name
to produce a valid 6to4 prefix. The first 16 bits of this prefix
will be replaced by
.B 2002
and the next 32 bits of this prefix will be replaced by the IPv4
address assigned to interface
.B name
at configuration time. The remaining 80 bits of the prefix (including
the SLA ID) will be advertised as specified in the configuration file.
See the next section for an example.

If interface
.B name
is not available at configuration time, a warning will be written to
the log and this prefix will be disabled until radvd is reconfigured.

This option enables systems with dynamic IPv4 addresses to update their
advertised 6to4 prefixes simply by restarting radvd or sending a SIGHUP
signal to cause radvd to reconfigure itself.

Note that 6to4 prefixes derived from dynamically-assigned IPv4 addresses
should be advertised with a significantly shorter lifetime (see the
.B AdvValidLifetime
and
.B AdvPreferredLifetime
options).

For more information on 6to4, see RFC 3056.

Default: 6to4 is not used

.SH ROUTE SPECIFIC OPTIONS

.TP
.BR "AdvRouteLifetime " seconds "" | infinity

The lifetime associated with the route in units of seconds.
The symbolic value
.B infinity
represents infinity (i.e. a value of all one bits (0xffffffff)).

Default: 3 * MaxRtrAdvInterval

.TP
.BR AdvRoutePreference " " low | medium | high

The preference associated with the default router, as either "low",
"medium", or "high".

Default: medium

.SH RDNSS SPECIFIC OPTIONS

.TP
.BR "AdvRDNSSPreference " integer;

The preference of the DNS server, compared to other DNS servers advertised and used.
0 to 7 means less important than manually configured nameservers in resolv.conf, while 12 to 15 means more important.

Default: 8

.TP
.BR "AdvRDNSSOpen " on | off;

"Service Open" flag. When set, indicates that RDNSS continues to be available to hosts even if they moved to a different subnet.

Default: off

.TP
.BR "AdvRDNSSLifetime " seconds | infinity;
The maximum duration how long the RDNSS entries are used for name resolution. A value of 0 means the nameserver should no longer be used.
The maximum duration how long the RDNSS entries are used for name resolution. A value of 0 means the nameserver should no longer be used.
The value, if not 0, must be at least MaxRtrAdvInterval.  To ensure stale
RDNSS info gets removed in a timely fashion, this should not be greater than
2*MaxRtrAdvInterval.

Default: 2*MaxRtrAdvInterval

.SH EXAMPLES

.nf
interface eth0
{
        AdvSendAdvert on;
        prefix 2001:db8:0:1::/64
        {
                AdvOnLink on;
                AdvAutonomous on;
        };
};
.fi

It says that router advertisement daemon should advertise
(AdvSendAdvert on;) the prefix 2001:db8:0:1:: which has a lenght of 64
on the interface eth0.  Also the prefix should be marked as autonomous
(AdvAutonomous on;) and as on-link (AdvOnLink on;).  All the other
options are left on their default values.

To support movement detection of Mobile IPv6 Mobile Nodes, the
address of interface should be used instead of network prefix:

.nf
interface eth0
{
        AdvSendAdvert on;
        prefix 2001:db8:0:1::4/64
        {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};
.fi

For 6to4 support, include the
.B Base6to4Interface
option in each prefix section. When using a dynamic IPv4 address, set
small prefix lifetimes to prevent hosts from retaining unreachable
prefixes after a new IPv4 address has been assigned.  When advertising to on
a dynamic interface (e.g., Bluetooth), skip the interface if it is not
active yet.

.nf
interface bnep0
{
        IgnoreIfMissing on;
        AdvSendAdvert on;

        # Advertise at least every 30 seconds
        MaxRtrAdvInterval 30;

        prefix 0:0:0:5678::/64
        {
                AdvOnLink on;
                AdvAutonomous on;
                Base6to4Interface ppp0;

                # Very short lifetimes for dynamic addresses
                AdvValidLifetime 300;
                AdvPreferredLifetime 120;
        };
};
.fi

Since 6to4 is enabled, the prefix will be advertised as
2002:WWXX:YYZZ:5678::/64, where WW.XX.YY.ZZ is the IPv4 address of
ppp0 at configuration time. (IPv6 addresses are written in hexadecimal
whereas IPv4 addresses are written in decimal, so the IPv4 address
WW.XX.YY.ZZ in the 6to4 prefix will be represented in hex.)

In this specific case, the configuration scripts may send HUP signal to
radvd when taking bnep0 up or down to notify about the status; in the
current radvd releases, sending HUP is no longer mandatory when the link
comes back up.

.TH RADVDUMP 8 "29 Dec 2001" "radvd @VERSION@" ""
.SH NAME
radvdump \- dump router advertisements
.SH SYNOPSIS
.B radvdump
.B "[ \-vhfe ]"
.BI "[ \-d " debuglevel " ]"

.SH DESCRIPTION
.B radvdump
prints out the contents of incoming router advertisements sent by
.B radvd
or some other software implementing (parts of)
"Neighbor Discovery for IP Version 6 (IPv6)" (RFC 2461).

.SH OPTIONS

For every one character option there is also a long option, which
is listed right next to the "short" option name:

.TP
.BR "\-v" , " \-\-version"
Displays the version of
.I radvdump
and then aborts.
.TP
.BR "\-h" , " \-\-help"
Displays a short usage description and then aborts.
.TP
.BR "\-f" , " \-\-file\-format"
Output received router advertisements in the format of the
.B radvd
configuration file.
Since radvd 0.9, this is the default and the switch is provided
for backward compatibility only.
.TP
.BR "\-e" , " \-\-exclude-defaults"
Exclude default valued options from configuration file format.
This option is ignored if option
.B "\-f"
is not set.
.TP
.BR "\-d " debuglevel, " \-\-debug " debuglevel
With this option you turn on debugging information. The debugging level is
an integer in the range from 1 to 4, from quiet to very verbose. A
debugging level of 0 completely turns off debugging.

The default debugging level is 0.
