RP Support on MCT Cluster Devices
MCT cluster devices can be configured to be an RP for multicast groups. Any one peer device can act as an RP. This can be used to facilitate traffic flow between source and receiver. For example, a receiver can join a multicast group after contacting the RP to show it is interested in the multicast group. Similarly, a source device can send traffic to an RP. The RP consolidates all traffic received from source and receiver devices, forwarding traffic as necessary.
Therefore, the RP acts as a meeting point for source and receiver devices. Sample MCT Configuration in a 3-tier Architecture shows an MCT deployment where an MCT cluster device is configured for an RP.
Configuration Example: Multicast Routing with an RP
The following example shows the configuration for multicast snooping where an MCT cluster device is configured as an RP, as depicted in Sample MCT Configuration in a 3-tier Architecture.
