The IESG has approved the following document: - 'OSPF Stub Router Advertisement' (draft-ietf-ospf-rfc3137bis-04.txt) as Informational RFC This document is the product of the Open Shortest Path First IGP Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ospf-rfc3137bis/ Technical Summary This document describes a backward-compatible technique that may be used by OSPF (Open Shortest Path First) implementations to advertise unavailability to forward transit traffic or to lower the preference level for the paths through such a router. This document updates RFC3137 to include applicability to OSPFv3. Working Group Summary There were some noteworthy discussions around including an alternate solution in OSPFv3 which achieves some of the same goals as RFC3137. Authors added a section to capture the use of R-bit as a potential alternative solution. R-bit is part of base OSPFv3 (RFC2740). Document Quality The incremental update to RFC3137 are minimal and the application to OSPFv3 is identical to OSPFv2. Personnel Abhay Roy is the document shepherd and Stewart Bryant is the responsible AD.
