Description of Working Group:

The MSDP working group will be charged with standardizing MSDP, the
Multicast Source Discovery Protocol. MSDP is a near-term solution for
connecting shared trees without the need for inter-domain shared trees
(it is envisioned that the Border Gateway Multicast Protocol, BGMP, is
the long term solution). MSDP is applicable to shared tree protocols
such as PIM-SM and CBT, as well as other protocols that keep active
source information at the borders (e.g., MOSPF or PIM-DM with DWRs).
This working group will interact closely with both MBONED where
operational issues arise, and IDMR where necessary for protocol issues.

Finally, it is envisioned that this working group will have a fairly
short live span.

Goals and Milestones:

Done    Hold the first Working Group meeting and discuss the charter and the state of progress on the chartered items.
Done    Submit MSDP Internet-Draft to IESG for consideration as a Proposed Standard.
Done    Submit MSDP specifications to IESG for consideration as Draft Standard.
Done    Submit MSDP Applicability Statement to IESG for publication as an RFC.
Apr 99    Submit MSDP MIB to IESG for consideration as proposed standard.
