Has anyone had any experience running multicast on the Cisco 3200 Mobile Access Routers?
We have some 3200s with the 4 port Fast Ethernet Switch Module (FESMIC). When we set up Vlans on the FESMIC, and enable multicast globally and PIM on the Vlan interfaces, we can see the multicast hosts respond to the IGMP querries from the router, and join the multicast groups, but multicast traffic (even between two directly connected hosts on different Vlans on the same FESMIC) doesn't get forwarded.
If I do a "show ip igmp group" I can see the hosts joinging the multicast goup fine. But if I do a "show ip mroute" I don't see the router forwarding any multicast data.
Strangely engough, I can't get it working until I issue a "ip igmp static-group..." command on the Vlan interface.
I have also tried to turn off multicast route-caching, but it doesn't work without the static join.
I have also seen this on a 3745 with a 16 port Ethernet switch module.
Anyone else possibly seen this?
