    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.
    Mar 2005  Submit PIMv2 MIB to IESG for consideration as draft standard.
