Hi, I have done a routing directorate review of this draft. https://datatracker.ietf.org/doc/draft-ietf-lsr-isis-rfc5306bis/ The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft. Document: draft-ietf-lsr-isis-rfc5306bis Reviewer: Manav Bhatia Review Date: 7 Dec 2018 Intended Status: Proposed Standard Summary: No issues found. This document is ready for publication. Comments: I have a minor comment on whether the authors could add some text that explains that the current mechanism only works when the restarting router comes up in a short amount of time, which is basically for as long as the Holdtimer does not expire on its neighbors. However, some restarts can take longer, and this adds support for such restarts. Thanks, Manav
