Charter charter-ietf-pim-07

The Protocol Independent Multicast (PIM) Working Group has completed
  the standardization of PIM with RFC 4601. The WG has determined there
  is additional work to be accomplished and is chartered to standardize
  extensions to RFC 4601 - Protocol Independent Multicast Version 2 -
  Sparse Mode. These PIM extensions will involve reliability, resiliency,
  scalability, management, and security.
  If L2VPN or L3VPN WGs determine that support for multicast in L2VPNs
  and/or L3VPNs requires extensions to PIM, then such extensions will be
  developed within the PIM WG.
  Additional work on the PIM-BIDIR and BSR drafts may also be necessary
  by the WG as these drafts progress through Standards Track.
  The working group has produced MIB modules for PIM in RFC 5060 and
  RFC 5240.  The working group currently has no plans to do further work
  on management for PIM. If proposals are brought forward to update or
  extend the existing MIB modules or to develop YANG modules, the working
  group will be rechartered.
  The PIM WG will further enhance RFC4601 as an even more scalable,
  efficient and robust multicast routing protocol, which is capable of
  supporting thousands of groups, different types of multicast
  applications, and all major underlying layer-2 subnetwork technologies.
  We will accomplish these enhancements by submitting drafts, to the
  IESG, involving reliable pim, pim join attributes and pim
  The working group primarily works on extensions to PIM, but may take on
  work related to IGMP/MLD.
  There is a significant number of errata that need to be addressed in
  order to advance RFC4601 to Draft Standard. The PIM WG will correct the
  errata, as necessary, and update RFC4601.
  The working group will initiate a new re-chartering effort if it is
  determined that a Version 3 of PIM is required.
