Anthony,

Sorry. I said that the commands are done in global config, but the ip pim sparse-dense-mode command is an interface command. I don’t have a Layer3 switch at my fingertips, so I can’t test to see if you can apply it to a VLAN interface, but you certainly can apply it to a router interface on a Layer3 switch. You also can apply it to a routers interface.

Here’s a link to Configuring Multicast Routing in 12.2 (which also applies to 12.3).

Hope it helps,

Wayne

hey guys,

Yeh i was unable to get it to work. Any more ideas? As for the “ip pim sparse-dense-mode” it seems i dont have that command in my version of IOS. Which is 12.3.

All the text on igmp was great but didnt get me where i need to be.

I am sure i am not the only persons trying to multicast symantec ghost via a cisco router.

Thanks guys

Depending on the defaults of the 3COMs, you might need to enable multicast routing on the router and set it to sparse-dense mode. Those commands are “ip multi-cast routing” and “ip pim sparse-dense-mode.” These commands are done in global config.
