Description of Working Group:

The Protocol Independent Multicast (PIM) Working Group is chartered to standardize and promote the Protocol Independent Multicast Version 2 (PIMv2), Sparse Mode and Dense Mode, as a scalable, efficient and robust multicast routing protocol, capable of supporting thousands of groups, different types of multicast applications, and all major underlying layer-2 subnetwork technologies. The working group will decide if there is a need for any follow on work or version 3 of the protocol.

This working group will act as a consultant to any PIM-over-Foo proposals, including but not limited to PIM-over-ATM, using PIM for multiprotocol label switching, and PIM-over-UDLR links.
