ROUTE6D(8)              OpenBSD System Manager's Manual             ROUTE6D(8)

NAME
     route6d - RIP6 routing daemon

SYNOPSIS
     route6d [-aDdhlnqSs] [-A prefix/preflen,if1[,if2,...]]
             [-L prefix/preflen,if1[,if2,...]] [-N if1[,if2,...]]
             [-O prefix/preflen,if1[,if2,...]] [-R routelog]
             [-T if1[,if2,...]] [-t tag]

DESCRIPTION
     The route6d utility is a routing daemon which supports RIP over IPv6.

     The options are as follows:

     -A prefix/preflen,if1[,if2,...]
             This option is used for aggregating routes.  prefix/preflen spec-
             ifies the prefix and the prefix length of the aggregated route.
             When advertising routes, route6d filters specific routes covered
             by the aggregate and advertises the aggregated route
             prefix/preflen to the interfaces specified in the comma-separated
             interface list if1[,if2,...].  route6d creates a static route to
             prefix/preflen, with the RTF_REJECT flag set, into the kernel
             routing table.

     -a      Enables aging of the statically defined routes.  With this op-
             tion, any statically defined routes will be removed unless corre-
             sponding updates arrive as if the routes are received at the
             startup of route6d.

     -D      Enables extensive output of debugging messages.  This option also
             instructs route6d to run in foreground mode (i.e. it does not
             become a daemon process).

     -d      Enables output of debugging messages.  This option also instructs
             route6d to run in foreground mode (i.e. it does not become a
             daemon process).

     -h      Disables split horizon processing.

     -L prefix/preflen,if1[,if2,...]
             Filter incoming routes from interfaces if1[,if2,...].  route6d
             will accept incoming routes that are in prefix/preflen.  If mul-
             tiple -L options are specified, all routes that match any of the
             options are accepted.  ::/0 is treated specially as the default
             route, not ``any route that has longer prefix length than, or
             equal to, 0''.  For example, with ``-L 3ffe::/16,if1 -L
             ::/0,if1'', route6d will accept the default route and routes in
             the 3ffe::/16 address range, but no others.  To accept any route,
             simply do not specify the -L option.

     -l      By default, route6d will not exchange site local routes for safe-
             ty reasons.  This is because the semantics of site local address
             space are rather vague, as the specification is still being
             worked on, and there is no good way to define the site local
             boundary.  With -l, route6d will exchange site local routes as
             well.  It must not be used on site boundary routers, since -l as-
             sumes that all interfaces are in the same site.

     -N if1[,if2,...]
             Do not listen to, or advertise, route from/to interfaces speci-
             fied by if1[,if2,...].

     -n      Do not update the kernel routing table.

     -O prefix/preflen,if1[,if2,...]
             Restrict route advertisement toward interfaces specified by
             if1[,if2,...].  With this option route6d will only advertise
             routes that match prefix/preflen.

     -q      Makes route6d use listen-only mode.  No advertisement is sent.

     -R routelog
             This option makes route6d log route changes (add/delete) to the
             file routelog.

     -S      This option is the same as -s, except that the split horizon rule
             does apply.

     -s      Makes route6d advertise the statically defined routes which exist
             in the kernel routing table when route6d is invoked.  Announce-
             ments obey the regular split horizon rule.

     -T if1[,if2,...]
             Advertise only the default route toward if1[,if2,...].

     -t tag  Attach the route tag tag to originated route entries.  tag can be
             decimal, octal prefixed by 0, or hexadecimal prefixed by 0x.

     Upon receipt of signal SIGINT or SIGUSR1, route6d will dump the current
     internal state into /var/run/route6d_dump.

FILES
     /var/run/route6d_dump  Contains the internal state dumps created if
                            route6d receives a SIGINT or SIGUSR1 signal.

NOTES
     route6d uses the advanced IPv6 API, defined in RFC 2292, for communicat-
     ing with peers using link-local addresses.

     Internally route6d embeds interface identifiers into bits 32 to 63 of
     link-local addresses (fe80::xx and ff02::xx) so they will be visible in
     the internal state dump file (/var/run/route6d_dump).

     Routing table manipulation differs from IPv6 implementation to implemen-
     tation.  Currently route6d obeys the WIDE Hydrangea/KAME IPv6 kernel, and
     will not be able to run on other platforms.

     Currently, route6d does not reduce the rate of the triggered updates when
     consecutive updates arrive.
