Technical Summary
This draft describes the extensions to OSPF link-local signalling
(LLS) to advertise the Local Interface Identifier.
Working Group Summary
There was initially some contention as to whether interface ID
discovery via OSPFv2 LLS was required given that the interface ID
can be advertised via OSPF GMPLS TE extensions [RFC4203]. However,
given that the advantages of fewer LSAs, discovery concurrent with
neighbor discovery, and incompatibilities with implementations
adding nodes to the TE topology, the consensus was to advance this
simple mechanism. Additionally, both IS-IS and OSPFv3 have similar
hello-based interface ID discovery.
