Charter for Working Group

This working group will extend the OSPF routing protocol so that it
will be able to efficiently route IP multicast packets. This will
produce a new (multicast) version of the OSPF protocol, which will be
as compatible as possible with the present version (packet formats and
most of the algorithms will hopefully remain unaltered).

Milestones

Done
The group should have a draft specification. Discuss the specification and make any necessary changes. Discuss implementation methods, using as an example, the existing BSD OSPF code, written by Rob Coltun of the University of Maryland.
Done
Become familiar with the IGMP protocol as documented in RFC 1112. Survey existing work on multicast routing, in particular, Steve Deering's paper ``Multicast Routing in Internetworks and Extended LANs''. Identify areas where OSPF must be extended to support multicast routing. Identify possible points of contention.
Done
Review outline of proposed changes to OSPF. Identify any unresolved issues and, if possible, resolve them.
Done
Report on implementations of the new multicast OSPF. Fix any problems in the specification that were found by the implementations.
Done
Submit the MOSPF Specification to the IESG as a Proposed Standard.
Jun 1996
Update MOSPF to reflect current usage, document interoperability between implementations, and submit to the IESG for consideration as a Draft Standard.
Dec 1996
Document interoperability between MOSPF and DVMRP, and submit as an Informational RFC.
Dec 1996
Submit MOSPF to IESG for consideration as a Standard.
