Hi all,
Can an IGMPv2 host respond to a general query originated from a subnet othe=
r then its own?? RFC 2236 states:
""query received" occurs when the host receives either a valid
General Membership Query message, or a valid Group-Specific
Membership Query message. To be valid, the Query message must be
at least 8 octets long, and have a correct IGMP checksum. The
group address in the IGMP header must either be zero (a General
Query) or a valid multicast group address (a Group-Specific Query)"
There is no requirement for the source address to be on the same subnet as =
the host.
Thanks,
Kunal
