route6d -- RIP6 routing daemon
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...]]
The route6d is a routing daemon which supports RIP over IPv6.
-a Enables aging of the statically defined routes. With this
option, any statically defined routes will be removed unless cor-
responding updates arrive as if the routes are received at the
startup of route6d.
This option makes route6d log route changes (add/delete) to the
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
-d Enables output of debugging messages. This option also instructs
route6d to run in foreground mode (i.e., it does not become a
-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).
-h Disables split horizon processing.
-l By default, route6d 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 -l, route6d will exchange site local routes
as well. It must not be used on site boundary routers, since -l
assumes that all interfaces are in the same site.
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 default
route, not ``any route that has longer prefix length than, or
equal to 0''. If you would like to accept any route, specify no
-L option. For example, with ``-L 3ffe::/16,if1 -L ::/0,if1''
route6d will accept the default route and routes in the 6bone
test address range, but no others.
-n Do not update the kernel routing table.
Do not listen to, or advertise, route from/to interfaces speci-
fied by 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.
-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.
-S This option is the same as -s, except that the split horizon rule
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.
/var/run/route6d_dump contains the internal state dumps created if
route6d receives a SIGINT or SIGUSR1 signal
G. Malkin and R. Minnear, RIPng for IPv6, RFC 2080, January 1997.
route6d uses the advanced IPv6 API, defined in RFC 3542, 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.
