Hi, I was reading RFC 4541 and i have a few doubts. I would really appreciate if somebody could help me clear those. According to Section 2.1.11 - "A snooping switch should forward IGMP Membership Reports only to those ports where multicast routers are attached." I understand that this would mean that a snooping switch should send all IGMP Membership Reports that it receives from its customer ports on to the pseudowire (PW) that connects this switch to the other PE routers. Is this correct? According to 2.1.2. Data Forwarding Rules - " 1) Packets with a destination IP address outside 224.0.0.X which are not IGMP should be forwarded according to group-based port membership tables and must also be forwarded on router ports." Does this mean that a snooping switch should forward packets with dest IP outside 224.0.0.X (which are not IGMP) only on the ports over which it has recvd a prior IGMP report + the PW that conects it to other PE routers? Thank You, Sriram
