This is my setup:
source-----C2955-------C3200------receiver-2 | receiver-1
The Cisco 3200 is configured with two VLANs; ip routing and multicast routing are enabled. Each VLAN is configured with ip pim sparse-dense-mode.
Port fa2/0 on the router belongs to VLAN 1. It connects to a Cisco2955 where the multicast source (video) and receiver-1 reside. The 2955 is acting as a hub. Port fa2/1 belongs to VLAN 2 and it connects to receiver-2.
Both receivers can view video but not at the same time. Receiver-2 can view video only if receiver-1 isn't streaming.
Any help is appreciated. Thanks.
