Anycast RP Support for MCT Cluster Devices

MCT cluster devices can be configured as anycast RP peers, thus providing redundancy to the RP.

RP is necessary in a PIM domain. Therefore, if the cluster peer which is an RP goes down, PIM can continue to function as both cluster peers are configured as RPs. Sample MCT Configuration in a 3-tier Architecture shows an MCT deployment where MCT cluster devices are configured for anycast RPs.

Configuration Example: Multicast Routing with Anycast RPs

The following example shows the configuration for multicast snooping where MCT cluster devices are configured as anycast RPs, as depicted in Sample MCT Configuration in a 3-tier Architecture.
