The switch listens to the following messages in order to detect router ports

· IGMP Membership query send to 01?00?5e?00?00?01
· PIMv1 hello send to 01?00?5e?00?00?02
· PIMv2 hello send to 01?00?5e?00?00?0d
· DVMRP probes send to 01?00?5e?00?04
· MOSPF message send to 01?00?5e?00?05 or 06
Thanks for clarifying this. Indeed, with this information, IGMP snooping
should never be harmful for router-switch-router traffic.
That is not my experience.
