Cisco Sparse Multicast using a single layer 3 switch and multiple layer 2 devices
Posted on 2011-03-24
I am trying to understand multicast for sparse if RP need to be configured. I have a layer 3 switch and multiple vlans with several layer 2 switches connected to it.
An example would be if I have a source on vlan 2 and a client on vlan 3. Based on understanding, I would just need to enable multicast routing and ip pim sparse mode on the required vlans; not too sure if an RP is required since the traffic is within the layer 3 switch and layer 2 switches. An example of the network diagram is as follows:
Source ----- (vlan 1) ---layer 3 switch ------layer 2 switch----vlan 2----client PC
