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.


Documents:

 1) PIM-SM v2 specification (standards track)

    This document is a specification for Sparse Mode Protocol
    Independent Multicast.

 2) PIM-DM v2 speficication (standards track)

    This document is a specification for Dense Mode Protocol
    Independent Multicast.

 3) PIM MIB (standards track)

    This document contains the MIB definitions for PIMv2.

 Goals and Milestones:

   Done         Hold the first Working Group meeting and discuss the charter 
                and the state of progress on the chartered items. 

   Done         Update the PIM-DM version 2 Internet-draft. Go to WG last call. 
                Submision to IESG for considerations as proposed standard. 

   Done         Resubmit the latest PIM-SM version 2 specification to IESG for 
                consideration as a proposed standard RFC 

   Done         Submit PIM-SM Applicability Statements 

   Done         Submit PIMv2 MIB to IESG for consideration as proposed 
                standard. 

   Done         Submit updated PIM-SM and PIM-DM internet-drafts, clarifying 
                any inconsistencies or ambiguities in the previous drafts. 

   Done         Submit PIM-SM version 2 and PIM-DM version 2 specifications to 
                IESG for consideration as Draft Standards. 

   Done         Submit PIMv2 MIB to IESG for consideration as draft standard.
