PIM6SD(8)               FreeBSD System Manager's Manual              PIM6SD(8)

NAME
     pim6sd - PIM for IPv6 sparse mode daemon

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

DESCRIPTION
     pim6sd is an IPv6 multicast routing daemon, which supports PIMv2(Protocol
     Independent Multicast Version 2) sparse mode and SSM(Source-Specific-
     Multicast) 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
             arguments, 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
             debugging use.

     pim6sd automatically configures itself to forward on all multicast-
     capable 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
     commands 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.

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

HISTORY
     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
     University.

BUGS
     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
     order 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
     address.

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