Hi,
Can someone please help me with this issue:
3Com 5500G-EI configured as layer-2 only does not forward multicast. Igmp-snooping does not report any groups.
The layer-3 multicast router and igmp querier is a Cisco router which is connected to the 3Com layer-2 switch.
However, if I do not use the Cisco router, and instead configure the 3Com 5500G-EI as layer-3 and let the 3Com do the igmp queries, multicast works. So the problem is clearly related to interoperability between Cisco layer-3 and 3Com layer-2.
Any ideas?
