Obviously as co-author I support this. This modest extension makes IS-IS GR usable for platforms which cannot reload within the normal adjacency hold-time. It also allows the helping neighbors to be aware that they have a restarting neighbor in case topology changes occur which would compromise the restarting node’s forwarding plane while the restart is in progress.
This achieves parity w functionality which has existed in OSPF for many years. It does NOT introduce interoperability issues w legacy nodes – though until the neighbors of the restarting node support this new functionality the benefits of the extension will not be realized.

Please post for review comments and/or support/objection to this document before 12:00 AM UTC on Tuesday, December 4th, 2018. Other than some RFC boiler plate changes, the RFC 5306 BIS document really only adds the PR/PA bit handling in section 2.2.3 and the addition of the Planned Restart State to sections 3.1 and 3.2. Thanks, Acee
