PIM6DD(8)

NAME
pim6dd - PIM for IPv6 dense mode daemon

SYNOPSIS
pim6dd [-c configfile] [-d [debug_level [,debug_level]]]

DESCRIPTION
pim6dd is an IPv6 multicast routing daemon, which supports PIMv2(Protocol Independent Multicast Version 2) dense mode for IPv6.

Options supported by pim6dd:

-c configfile
    Specify alternate location, configfile, for configuration file. By default, /usr/local/etc/pim6dd.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 timeout, packets, interfaces, kernel, mfc, pim_detail, pim_hello, kernel, mfc, pim_detail, pim_hello, pim_jp, pim_graft, pim_asserts, pim_routes, pim_timers, rpf, pim, routes, routers, timers, and asserts.

pim6dd 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/pim6dd.conf ( or an alternative file, specified by the ‘-c’ option). Note that pim6dd ignores interfaces that do not have an IPv6 address. Such interfaces should not appear in the configuration file.

FILES

HISTORY
The pim6dd command is based on pimdd, which is an IPv4 multicast routing daemon developed at the University of Oregon. pimdd has been derived from PIM sparse-mode pimd developed at University of Southern California. Part of these two programs above has also been derived from mrouted. mrouted is COPYRIGHT 1989 by The Board of Trustees of Leland Stanford Junior University.

BUGS
pim6dd 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 pim6dd in order to follow changes of existing unicast routes.

pim6dd must be used on an IPv6 router. Be sure to set net.inet6.ip6.forwarding variable to 1 with sysctl(8).
