ROUTE6D(8) FreeBSD System Manager's Manual ROUTE6D(8)
NAME route6d - RIP6 Routing Daemon
SYNOPSIS route6d [-adDhlnqsS] [-R routelog] [-A prefix/preflen,if1[,if2...]] [-L prefix/preflen,if1[,if2...]] [-N if1[,if2...]] [-O prefix/preflen,if1[,if2...]] [-P number] [-p pidfile] [-Q number] [-T if1[,if2...]] [-t tag]
DESCRIPTION The route6d utility is a routing daemon which supports RIP over IPv6.
Options are:
-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 route6d.
-R routelog This option makes the route6d to log the route change (add/delete) to the file routelog.
-A prefix/preflen,if1[,if2...] This option is used for aggregating routes. prefix/preflen specifies 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...]. The characters "*", "?", and "[" in the interface list will be interpreted as shell-style pattern. 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 daemon).
-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.
-L prefix/preflen,if1[,if2...] 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
-N if1[,if2...] Do not listen to, or advertise, route from/to interfaces specified by if1,[if2...].
-O prefix/preflen,if1[,if2...] Restrict route advertisement toward interfaces specified by if1,[if2...]. With this option route6d will only advertise routes that matches prefix/preflen.
-P number Specifies routes to be ignored in calculation of expiration timer. The number must be 1, 2, or 3 and it means route flags of RTF_PROTO1, RTF_PROTO2, or RTF_PROTO3. When 1 is specified, routes with RTF_PROTO1 will never expire.
-p pidfile Specifies an alternative file in which to store the process ID. The default is /var/run/route6d.pid.
-Q number Specifies flag which will be used for routes added by RIP protocol. The default is 2 (RTF_PROTO2).
-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.
-T if1[,if2...] 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.
FILES /var/run/route6d_dump dumps internal state on SIGINT or SIGUSR1
SEE ALSO G. Malkin and R. Minnear, RIPng for IPv6, RFC2080, January 1997.
NOTE The route6d utility uses IPv6 advanced API, defined in RFC2292, for communicating 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 internal state dump file (/var/run/route6d_dump).
Routing table manipulation differs from IPv6 implementation to implementation. Currently route6d obeys WIDE Hydrangea/KAME IPv6 kernel, and will not be able to run on other platforms.
