Multicast and etherchannel

Just double checking, but the 'ip pim-sparse mode' commands go on the portchannel interface and not the individual interfaces in the portchannel right?

I presume we are talking about a layer-3 EtherChannel here, i.e. no switchport.

Then the answer is yes, ip pim sparse-mode goes on the Po interface.

That's what I thought - it always goes on the L3 interface which the port channel is. Thanks for confirming that for me.

Re: Multicast and etherchannel

Hi

Catalyst 3750 stack will be running IP Base  image configured as EIGRP stub with one physical link to two 6500  switches. Catalyst 6500 combined to form VSS. Hence connection between  3750 stack and VSS will be a  single layer 3 logical connection  (Layer 3  Port Channel).

Multicast Stub (PIM-DM) will be configured on the Port  Channel interface at both ends of the EtherChannel link with the VSS  end configured for passive mode.

Should this work?

Has anybody got this working?

Thanks
