Reviewer: IJsbrand Wijnands Review result: Has Issues Hi All, I have been selected to do a routing directorate QA review of this draft. https://www.ietf.org/id/draft-ietf-ospf-ospfv3-lsa-extend-14.txt Summary: This draft proposes a new addressing (TLV) format to more easily allow additional information to be added as part of a particular LSA. Overall, well written, easy to understand what the objective is for this draft. Comments and Questions: This looks like a pretty radical change to the OSPFv3 spec. I would almost argue to call it OSPFv4.. Its very unfortunate there are no ‘reserved’ fields in RFC5340 that would allow you keep the existing LSA’s format and have some way to extend it differently. The TLV approach look good, I can’t see a better way to achieve the goal. Minor Issues and Nits: none. Thx, Ice.
