The IESG has approved the following document: - 'OSPFv2 Multi-Instance Extensions' (draft-ietf-ospf-multi-instance-09.txt) as a Proposed Standard This document is the product of the Open Shortest Path First IGP Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ospf-multi-instance/ Technical Summary This draft extends OSPFv2 to support multiple routing domains on the same subnet - a capability that already exists in OSPFv3. This is different from OSPFv3 where it could be used for other purposes such as putting the same interface in multiple areas. OSPFv2 supports this capability using a separate subnet or the OSPF multi-area adjacency capability. Working Group Summary The only discussion worth noting was the behavior of legacy routers receiving OSPF packets with non-Zero instance ID. It was concluded that the such packets would be misinterpreted as having mismatched authentication type and would get dropped. Such errors should get logged and should result in the generation of SNMP traps. There was concern that this could be an issue if every packet would result in SNMP trap generation. However, it was discussed that this will not be an issue since most implementations will damp the logging of errors and generation of identical SNMP traps. Document Quality There is one known implementation. Personnel Manav Bhatia is the Document Shepherd. Stewart Bryant is the Responsible Area Director. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
