Reviewer: Qin Wu Review result: Ready with nits I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. This document describes how to convey the RP address information into the MVPN Source Active route using an Extended Community so this information can be shared with an existing MSDP infrastructure. It provides an update to RFC6514. Major issues: None Minor issues: I am wondering how MVPN and MSDP SA Interoperation is back compatible with existing source discovery information dissemination methods? Is there any downside to make MVPN SA and MSDP SA work together. Section 1: Suggest to add term for GTM, RPT, C-Multicast Section 3 When we say MVPN Pes that have one or more MSDP session in a VPN, does this statement contradict with “VPN-specific MSDP sessions are not required among the PEs”? Section 3 What do you mean other MSDP speaker? Do we assume there is one or only one MSDP speaker in the MSDP mesh group? How MSDP speaker is different from MSDP peer? Do you mean there is no session to be established between MSDP peer? Section 3, last paragraph: When we say ” In that case, if the selected best MVPN SA route does not have the "MVPN SA RP-address EC" but another route for the same (C-S, C-G) does, then the best route with the EC SHOULD be chosen.”, which best route is selected? Selected best MVPN SA route without EC or normal route with the EC? It looks you assume the normal route with the EC is the best selected route as well in this context? Section 3 Can you provide an example of fine grained policy control? Is this related to local policy? “accepted MSDP SA message when receiving PE’s RP for the C-G is MSDP peer to which the generated MSDP message is advertised”
