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.
