Pimd | the PIM-SM V2 Daemon

pimd is a lightweight stand-alone PIM-SM v2 multicast routing daemon. It is the original USC (netweb/catarina.usc.edu) implementation of the protocol, according to RFC 2362.

Thanks to OpenBSD freeing mrouted, pimd is now also fully free to use under the 3-clause BSD license.

Protocol Independent Multicast, PIM, allows existing networks to route IP multicast, regardless of what unicast routing protocol is in use. It is designed to use the existing routing tables to make its multicast routing decisions. PIM-SM is suitable for sparsely located multicast subscribers, for dense mode operation mrouted is recommended.

pimd was written by Ahmed Helmy, George Edmond “Rusty” Eddy, and Pavlin Ivanov Radoslavov. With contributions by many others.
