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
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.
