Sh DESCRIPTION
The
Nm
is a routing daemon which supports RIP over IPv6.
Pp
Options are:
Bl -tag -width indent
\"
It Fl a
Enables aging of the statically defined routes.
With this option, any
statically defined routes will be removed unless corresponding updates
arrive as if the routes are received at the startup of
Nm .
\"
It Fl R Ar routelog
This option makes
Nm
log route changes (add/delete) to the file
Ar routelog .
\"
It Fl A Ar prefix/preflen,if1[,if2...]
This option is used for aggregating routes.
Ar prefix/preflen
specifies the prefix and the prefix length of the
aggregated route.
When advertising routes,
Nm
filters specific routes covered by the aggregate
and advertises the aggregated route
Ar prefix/preflen
to the interfaces specified in the comma-separated interface list
Ar if1[,if2...] .
Nm
creates a static route to
Ar prefix/preflen ,
with the
Dv RTF_REJECT
flag set, into the kernel routing table.
\"
It Fl d
Enables output of debugging messages.
This option also instructs
Nm
to run in foreground mode
Pq i.e., it does not become a daemon process .
\"
It Fl D
Enables extensive output of debugging messages.
This option also instructs
Nm
to run in foreground mode
Pq i.e., it does not become a daemon process .
\"
It Fl h
Disables split horizon processing.
\"
It Fl l
By default,
Nm
will not exchange site local routes for safety 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
Fl l ,
Nm
will exchange site local routes as well.
It must not be used on site boundary routers,
since
Fl l
assumes that all interfaces are in the same site.
\"
It Fl L Ar prefix/preflen,if1[,if2...]
Filter incoming routes from interfaces
Ar if1,[if2...] .
Nm
will accept incoming routes that are in
Ar prefix/preflen .
If multiple
Fl L
options are specified, all routes that match any of the options are accepted.
Li ::/0
is treated specially as default route, not
Do
any route that has longer prefix length than, or equal to 0
Dc .
If you would like to accept any route, specify no
Fl L
option.
For example, with
Do
Fl L
Li 3ffe::/16,if1
Fl L
Li ::/0,if1
Dc
Nm
will accept the default route and routes in the 6bone test address range,
but no others.
\"
It Fl n
Do not update the kernel routing table.
\"
It Fl N Ar if1[,if2...]
Do not listen to, or advertise, route from/to interfaces specified by
Ar if1,[if2...] .
\"
It Fl O Ar prefix/preflen,if1[,if2...]
Restrict route advertisement toward interfaces specified by
Ar if1,[if2...] .
With this option
Nm
will only advertise routes that match
Ar prefix/preflen .
\"
It Fl q
Makes
Nm
use listen-only mode.
No advertisement is sent.
\"
It Fl s
Makes
Nm
advertise the statically defined routes which exist in the kernel routing
table when
Nm
is invoked.
Announcements obey the regular split horizon rule.
\"
It Fl S
This option is the same as
Fl s ,
except that the split horizon rule does apply.
\"
It Fl T Ar if1[,if2...]
Advertise only the default route toward
Ar if1,[if2...] .
\"
It Fl t Ar tag
Attach the route tag
Ar tag
to originated route entries.
Ar tag
can be decimal, octal prefixed by
Li 0 ,
or hexadecimal prefixed by
Li 0x .
\"
El
Pp
Upon receipt of signal
Dv SIGINT
or
Dv SIGUSR1 ,
Nm
will dump the current internal state into
Pa /var/run/route6d_dump .
\"
Sh FILES
Bl -tag -width /var/run/route6d_dump -compact
It Pa /var/run/route6d_dump
contains the internal state dumps created if
Nm
receives a
Dv SIGINT
or
Dv SIGUSR1
signal

Sh NOTES
Nm
uses the advanced IPv6 API,
defined in RFC 3542,
for communicating with peers using link-local addresses.
Pp
Internally
Nm
embeds interface identifiers into bits 32 to 63 of link-local addresses
Po
Li fe80::xx
and
Li ff02::xx
Pc
so they will be visible in the internal state dump file
Pq Pa /var/run/route6d_dump .
Pp
Routing table manipulation differs from IPv6 implementation to implementation.
Currently
Nm
obeys the WIDE Hydrangea/KAME IPv6 kernel,
and will not be able to run on other platforms.
Pp
Currently,
Nm
does not reduce the rate of the triggered updates when consecutive updates
arrive.
