Document: draft-ietf-nvo3-hpvr2nve-cp-req-13.txt Reviewer: Brian Carpenter Review Date: 2018-02-07 IETF LC End Date: 2018-02-20 IESG Telechat date: 2018-02-22 Summary: Ready (with minor issue) -------- Comment: -------- This is a Last Call review despite the subject field. Minor issue: ------------ Req-10: The protocol MUST allow an End Device initiating a request to add, remove or update address(es) associated with a TSI instance on the external NVE. Addresses can be expressed in different formats, for example, MAC, IP or pair of IP and MAC. Here and elsewhere, it seems necessary to specify that an IP address can be in either IPv4 or IPv6 format. (This is implied in Table 1 and at the end of Appendix A, but that's quite well hidden.) I suggest clarifying this early, in Section 1.2 "Target Scenarios".
