Reviewer: Dan Romascanu Review result: Not Ready This is the OPS-DIR review of draft-ietf-bier-tether-05. This document specifies optional procedures to optimize the handling of Bit Index Explicit Replication (BIER) incapable routers, by attaching (tethering) a BIER router to a BIER incapable router. The document is quite clear in its scope and definition of the core functionality that is being added.However, this being a Standards Track document that extends an existing protocol, I believe that from an operational and manageability perspective it lacks any information. I believe that these should be included, either explicitly or by reference, possibly in an 'Operational and Manageability Considerations' section. See RFC 5706 for guidelines about the information that could be relevant. -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
