Document: draft-ietf-spring-segment-routing-ldp-interop-11 Reviewer: Joel Halpern Review Date: 2018-05-14 IETF LC End Date: 2018-05-24 IESG Telechat date: Not scheduled for a telechat Summary: This document appears to be ready for publication as an RFC. The question of whether it is an Informational RFC or a Proposed Standards track RFC is one that the ADs should examine. Major issues: This document is quite readable, and quite useful. If my reading below (minor comment about section 4.2) is wrong, then everything is fine. However, reading the text, it does not appear to define SRMS. Rather, it describes a good way to use SRMS to achive smooth SR - LDP integration and migration. As such, this seems to me to be a really good Informational Document. Minor issues: Section 4.2 states that it defines the SRMS (Segment Routing Mapping Server). Looking at the relevant routing protocol document, they point to https://tools.ietf.org/html/draft-ietf-spring-conflict-resolution-05 as the defining source for the SRMS. And that document does appear to define the SRMS. Nits/editorial comments:
