Dear RFC9251 Co-authors, Your help with the following questions will be most appreciated,
RFC 9251 seems to assume that the receiving PE will forward: 1. (S,G1) traffic only to those host who explicitly sent IGMPv3 report (S,G1) and those who sent IGMPv3 Report (*,G1) 2. (*,G1) traffic only to those host who explicitly sent IGMPv3 report (*,G1) IGMPv2(G1) Is this indeed the assumption? Does it mean that the receiving PE shall do an IP Multicast lookup ? i.e. Has MFIB entry with (S,G1)==> OIF( a, b, c ..) for all local AC ports from which IGMPv3 Report (S,G1) OR (*,G1)==> OIF( a, b, c ..) for all local AC ports from which IGMPv3 Report (*,G1) or IGMPv2 report (G1) Another issue: Referring to https://www.rfc-editor.org/rfc/rfc9251.html#name-proxy-querier It says that "As mentioned in the previous sections, each PE MUST have proxy querier functionality for the following reasons: 1. to enable the collection of EVPN PEs providing Layer 2 Virtual Private Network (L2VPN) service to act as a distributed multicast router with an anycast IP address for all attached hosts in that subnet 2. to enable suppression of IGMP Membership Reports and Membership Queries over MPLS/IP core" What shall be the source IP address of the IGMP queries? Possible Alternatives: 1. The source IP of one of the Routers on the related PE BD (if exists). 2. Some preconfigured dummy IRB Router Anycast IP address ?
