pimd(1) PIMv2-SM multicast routing daemon


pimd [options]


This manual page documents briefly the pimd program. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

pimd provides implementation of Protocol Independent Multicast v2 protocol which is used in todays Internet for routing multicast traffic. PIM is widely deployed because it is main multicast routing protocol used in Cisco routers.

The Protocol Independent Multicast--Sparse Mode (PIM-SM) architecture:

* maintains the traditional IP multicast service model of receiver-initiated membership;
* uses explicit joins that propagate hop-by-hop from members' directly connected routers toward the distribution tree.
* builds a shared multicast distribution tree centered at a Rendezvous Point, and then builds source-specific trees for those sources whose data traffic warrants it.
* is not dependent on a specific unicast routing protocol; and
* uses soft-state mechanisms to adapt to underlying network conditions and group dynamics.
The robustness, flexibility, and scaling properties of this architecture make it well suited to large heterogeneous internetworks.


These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. For more informations see project documentation.

pimd will use FILE as configuration file instead of /etc/pimd.conf
