route6d -- RIP6 Routing Daemon
route6d [-adDhlnqsS] [-R routelog] [-A prefix/preflen,if1[,if2...]]
[-L prefix/preflen,if1[,if2...]] [-N if1[,if2...]]
[-O prefix/preflen,if1[,if2...]] [-T if1[,if2...]] [-t tag]
The route6d utility 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 the route6d to log the route change
(add/delete) to the file routelog.
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-sepa-
rated interface list, if1[,if2...]. The route6d utility creates
a static route to prefix/preflen with RTF_REJECT flag, into the
kernel routing table.
-d Enables output of debugging message. This option also instructs
route6d to run in foreground mode (does not become daemon).
-D Enables extensive output of debugging message. This option also
instructs route6d to run in foreground mode (does not become dae-
-h Disables the split horizon processing.
-l By default, route6d will not exchange site local routes for
safety reasons. This is because semantics of site local address
space is rather vague (specification is still in being worked),
and there is no good way to define site local boundary. With -l
option, route6d will exchange site local routes as well. It must
not be used on site boundary routers, since -l option assumes
that all interfaces are in the same site.
Filter incoming routes from interfaces if1,[if2...]. The route6d
utility will accept incoming routes that are in prefix/preflen.
If multiple -L options are specified, any routes that match one
of the options is 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 default route and routes in 6bone test
address, 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 matches prefix/preflen.
-q Makes route6d in listen-only mode. No advertisement is sent.
-s Makes route6d to advertise the statically defined routes which
exist in the kernel routing table when route6d invoked.
Announcements obey the regular split horizon rule.
-S This option is the same as -s option except that no split horizon
rule does apply.
Advertise only default route, toward if1,[if2...].
-t tag Attach 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 dumps internal state on SIGINT or SIGUSR1
G. Malkin and R. Minnear, RIPng for IPv6, RFC2080, January 1997.
The route6d utility uses IPv6 advanced API, defined in RFC2292, for com-
municating with peers using link-local addresses.
Internally route6d embeds interface identifier into bit 32 to 63 of link-
local addresses (fe80::xx and ff02::xx) so they will be visible on inter-
nal state dump file (/var/run/route6d_dump).
Routing table manipulation differs from IPv6 implementation to implemen-
tation. Currently route6d obeys WIDE Hydrangea/KAME IPv6 kernel, and
will not be able to run on other platforms.
Current route6d does not reduce the rate of the triggered updates when
consecutive updates arrive.
