The IESG has received a request from the Open Shortest Path First IGP WG (ospf) to consider the following document: - 'OSPF Hybrid Broadcast and P2MP Interface Type' <draft-ietf-ospf-hybrid-bcast-and-p2mp-03.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2012-07-19. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document describes a mechanism to model a broadcast network as a hybrid of broadcast and point-to-multipoint networks for purposes of OSPF operation. Neighbor discovery and maintenance as well as LSA database synchronization are performed using the broadcast model, but the network is represented using the point-to-multipoint model in the router LSAs of the routers connected to it. This allows an accurate representation of the cost of communication between different routers on the network, while maintaining the network efficiency of broadcast operation. This approach is relatively simple and requires minimal changes to OSPF. This document updates both OSPFv2 [RFC2328] and OSPFv3 [RFC5340]. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-ospf-hybrid-bcast-and-p2mp/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-ospf-hybrid-bcast-and-p2mp/ballot/ No IPR declarations have been submitted directly on this I-D.
