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.
