[c-nsp] Multicast on a 6500 running ios

[Jensen Geir (UmoeIKT)]

Thanks Jeff,

I believe the "ip igmp snooping querier" requires a VLAN interface with
an ip address? For this particular vlan,  we want the 6500 to operate at
layer2.

Does this imply that the 6500 (running ios) can't use igmp snooping when
it's being used as a layer2-switch?

I'll try to disable igmp snooping.

Hi,

You should either enable igmp snooping querier on this VLAN or disable
igmp
snooping. 


To enable the IGMP querier in a VLAN, perform this task:
Step 1 Switch(config)# interface vlan vlan_ID 
Step 2 Switch(config-if)#ip igmp snooping querier Enable the IGMP
querier.
