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.
