Sorry if I don't answer your question, but there is very little information to
work on; I'll just post the theory I have:
>From RFC 2236, IGMP Version 2 (And yes, I do read the RFC's... I think
everyone should!)
"All multicast routers start up as a Querier on each attached network. If a
multicast router hears a Query message from a router with a lower IP address,
it MUST become a Non-Querier on that network."
In english, it means, on a broadcast medium (ethernet), only one router should
respond to join and leave requests (and be responsible for membership), this
is the one with the lower IP address on the segment.
I would hazard a guess tht your R2's ethernet address is lower than R1's
ethernet address.
