Technical Summary OSPFv2 requires functional extension beyond what can readily be done with the fixed-format Link State Advertisements (LSAs) as described in RFC 2328.This document defines OSPF opaque LSAs based on Type- Length-Value (TLV) tuples that can be used to associate additional attributes with prefixes or links. Working Group Summary There has been much discusson about the protocol operations when the extended prefix TLVs appear multiple times in the OPAQUE LSA and different flooding scope of the extended Prefix LSA. As a result of the discussion, the document has been updated with details of receive side handling for all the cases along with recommended behaviours for send side to minimize disruptions in the network. Document Quality This document has been a WG document for a little under one year. It is stable, without changes to the technical solution for more than three months. Additionally, the document has been successfully implemented by interoperability tested by multiple vendors as indicated by the implementation status section. Personnel Shraddha Hegde is the Document Shepherd. Alia Atlas is the Responsible Area Director. RFC Editor Note Please remove the Section 5 on Implementation Status.
