multicasting

I am trying to configure multicasting and I am having no luck. I have multicast enabled on the router and I also have IGMP enabled on the switch that it is connected to. I need multicast enabled for Paging to work on the network and I am having no luck. any ideas?

Re: multicasting

Syriean,

Could you please provide more information on your topology. Is there just one device involved? If so, a very common issue is that the TTL is set to 1 by default in many multicast applications, which prevents multicast streams to go from one L3 interface to another.

It would probably be worth checking that first.
