     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...]] [-P number] [-p pidfile]
	     [-Q number] [-T if1[,if2...]] [-t tag]

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

     Options are:

     -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.

     -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 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 characters "*", "?", and
	     "[" in the	interface list will be interpreted as shell-style pat-
	     tern.  The	route6d	utility	creates	a static route to
	     prefix/preflen with RTF_REJECT flag, into the kernel routing ta-

     -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.

     -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
	     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 2001:db8::/16,if1 -L ::/0,if1"
	     route6d will accept default route and routes in 6bone test	ad-
	     dress, but	no others.

     -n	     Do	not update the kernel routing table.

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

     -Q	number
	     Specifies flag which will be used for routes added	by RIP proto-
	     col.  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.  An-
	     nouncements 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.

     /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.
