     pim6sd -- PIM for IPv6 sparse mode	daemon

     pim6sd [-c	configfile] [-d	[debug_level [,debug_level]]] [-f]

     pim6sd is an IPv6 multicast routing daemon, which supports	PIMv2(Protocol
     Independent Multicast Version 2) sparse mode and SSM(Source-Specific-Mul-
     ticast) for IPv6.

     Options supported by pim6sd:

     -c	configfile
	     Specify alternate location, configfile, for configuration file.
	     By	default, /usr/local/etc/pim6sd.conf is used.

     -d	     Specify debug levels. If this option is specified without any ar-
	     guments, all debug	messages will be printed out.  A subset	of the
	     messages to be printed out	can be specified as arguments of the
	     option.  Valid debug levels are mld_proto,	mld_timer, mld_member,
	     mld, switch, trace, mtrace, traceroute, timeout, callout, pkt,
	     packets, interfaces, vif, kernel, cache, mfc, k_cache, k_mfc,
	     rsrr, pim_detail, pim_hello, pim_neighbors, pim_register,
	     registers,	pim_join_prune,	pim_j_p, pim_jp, pim_bootstrap,
	     pim_bsr, bsr, bootstrap, pim_asserts, pim_cand_rp,	pim_c_rp,
	     pim_rp, rp, pim_routes, pim_routing, pim_mrt, pim_timers,
	     pim_rpf, rpf, pim,	routes,	routing, mrt, routers, mrouters,
	     neighbors,	timers,	and asserts.

     -f	     Do	not become daemon, run in foreground. This option is for de-
	     bugging use.

     pim6sd automatically configures itself to forward on all multicast-capa-
     ble interfaces, i.e., interfaces that have	the IFF_MULTICAST flag set
     (excluding	the "loopback interface" and interaces that do not have	an
     IPv6 address).  To	override the default configuration, configuration com-
     mands may be placed in /usr/local/etc/pim6sd.conf (or an alternative
     file, specified by	the `-c' option).  If the multicast group address is
     within SSM-range (ff20::/12 and ff30::/12), pim6sd	will behaves as	an SSM
     routing daemon; speaking MLDv2 toward hosts and uses only Shortest	Path
     Tree for these multicast addresses.  Note that pim6sd ignores interfaces
     that do not have an IPv6 address.	Such interfaces	should not appear in
     the configuration file.

     The pim6sd	program	dumps its current routing information to a dump	file
     when it receives a	SIGUSR1	signal.	 The information includes a list of
     PIM neighbors, pim6sd internal multicast routing table, and BSR and RP
     related information. Also,	the program dumps its internal statistics to a
     file when it receives a SIGINFO signal.

     When pim6sd receives a SIGUSR2 signal, it rereads the configuration file
     and reset its debug level.

     The pim6sd	program	puts its logs to a separate file ~
     (/var/log/pim6sd.log).  The log level can be configured by	the -d command
     line option or the	configuration file.

     /usr/local/etc/pim6sd.conf	 The default configuration file.
     /var/run/pim6sd.dump	 The file to which pim6sd dumps	its internal
     /var/run/pim6sd.stat	 The file to which pim6sd dumps	its internal
     /var/log/pim6sd.log	 The pim6sd specific log file.

     daemon(3),	pim6sd.conf(5)

     The pim6sd	command	is developed by	Mickael	Hoerdt at LSIIT	Laboratory.
     It	is based on IPv4 PIM sparse-mode pimd developed	at University of
     Southern California, which	has also been derived from mrouted.  mrouted
     is	COPYRIGHT 1989 by The Board of Trustees	of Leland Stanford Junior Uni-

     pim6sd does not contain any unicast routing engine, so a unicast routing
     daemon needs to run on the	system.

     The kernel	unicast	routing	table is periodically polled by	pim6sd in or-
     der to follow changes of existing unicast routes.

     pim6sd must be used on an IPv6 router.  Be	sure to	set
     net.inet6.ip6.forwarding variable to 1 with sysctl(8).

     pim6sd requires the node running the daemon to have an IPv6 global	ad-

     pim6sd does not work properly when	interface is dynamically added or
     deleted (e.g. ifconfig gif0 create).
