Description of 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).

Goals and Milestones:

Done

  

Review outline of proposed changes to OSPF. Identify any unresolved issues and, if possible, resolve them.

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

  

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

  

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 96

  

Update MOSPF to reflect current usage, document interoperability between implementations, and submit to the IESG for consideration as a Draft Standard.

Dec 96

  

Submit MOSPF to IESG for consideration as a Standard.

Dec 96

  

Document interoperability between MOSPF and DVMRP, and submit as an Informational RFC.
