A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-ospf-lls-interface-id/ 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. Document Quality This document has been a WG document for more than 1 year and has had several good reviews.
