- CURRENT_MEETING_REPORT_
-
- Reported by Steve Deering/ Stanford
-
- Minutes:
-
- This was the second meeting of the Multicast OSPF Working Group.
-
- Steve Deering gave a short presentation on the cost and scaling aspects
- of IGMP (the Internet Group Management Protocol, specified in RFC-1112)
- and of link-state multicast routing as planned for OSPF. [See the
- accompanying slides.]
-
- John Moy presented an outline of the changes and additions required to
- the current OSPF specification, to support multicast routing.
- Discussion of his outline identified some new concerns and suggestions
- regarding:
-
-
- o support for multicast routing by only a subset of routers in an
- area and its effect on multicast vs. unicast reachability,
- selection of designated routers, etc.
- o duplicate multicast packets arising from the support of multiple IP
- subnets on a single physical network.
- o inter-area and inter-AS multicast routing approaches.
-
-
- It was also pointed out that we will have to come up with formal MIB
- definitions covering the additional state and configuration variables
- introduced for multicast routing. No one immediately volunteered for
- that job.
-
- Action Items
-
- John Moy to generate a draft of the multicast changes/additions to the
- OSPF specification.
-
- Next Meeting
-
- The Multicast OSPF Working Group will next meet in Vancouver, at the
- July/August IETF meeting.
