Hi,
I have attached a high level design diagram which represents the network topology and multicasting is introduced on the network for camera streams. For multicast using “sparse-dense-mode” and OSPF is used as the routing protocol.
Multicast works good when we had a single receiver “Receiver-1” and this receiver is connected to a access switch which directly connects to the core 6500 switch through a L3 Vlan. Mroutes looks good and works as expected.
When a second receiver “Receiver-2” was introduced on the network and the configuration is no different to the previous configuration and the receiver is not getting any streams and the multicast doesn’t work as expected. The only difference between is the presence of a L2 switch which acts as a bridge between the Access and the Core 6500 switch.
I believe, the simplest option is to enable routing and multicast on the switch called “Core-2” instead of using it as a L2 transparent switch. But, I would like to explore the possible options before enabling multicast throughout the network.
Your thoughts and help will be highly appreciated.
Thanks
Rajesh
