I am having some issues with Multicasting (basically not working). It is not working on the LAN, and am pretty confident that when I get the sorted out I will be able to get it sorted out on the WAN. Anyway, I have 4507 with 5 VLAN interfaces with ip pim sparse-mode under each interface, my first question is, when I do a show ip pim neighbor, shouldn't I see those interfaces?

PIM Neighbor Table
Neighbor Address Interface Uptime Expires Ver Mode
Nada. Secondly, there is a router attached who also has ip pim sparse-mode on its fast ethernet 0/0 interface. The 4507 is directly attached to this 7204 and I do not see it as a neighbor. I should note that the 4507 and 7204 do not have an interface in the same subnet. I think If I change the IP of the 7204 and make it an access port on the 4507 it may come up as a neighbor.
