I have a multicast "client" sending a join request to a multicast group on vlan 11.
The multicast source sending the multicast is on vlan 120.
I use a L-3 switch Catalyst 3550 using PIM-DENSE mode configure on these two vlan interfaces.
the join request does NOT stop at the routing engine on the switch and is being forwarded to vlan 120 as flooding.
multicast traffic does NOT reaching the client unless I push the multicast traffic to the interface of the client.
It looks that the L-3 switch does not recognize the structure of the join message.
IGMP Snooping is configured.
Any idea what can be done to make the multicast work "normally"?
