Hi Hitoshi,

         Yes. Querier need not be a multicast data forwarder. But are you suggesting that a forwarder who is not a IGMP querier process the leave message? If yes, what action do they take?

         As per RFC 2236, non-querier should be using group specific queries to lower down the group timer instead of leave messages.

Regards,
Bharat

PS: Sorry for not able to reply inline.

And also, querier is not always forwarder.
