The PIM implementation within the vRouter supports the embedded-rendezvous (RP) feature. This mechanism defines an address-allocation policy in which the address of the RP is encoded in a multicast group address. When PIM sparse mode is configured, the embedded rendezvous-point IPv6 feature can be used as the specification for a group-to-RP mapping mechanism.
To support embedded RP, the router configured as the RP must use a configured access list that permits the embedded RP group ranges derived from the embedded RP address. If embedded RP support is available, only the RP must be statically configured as the RP for the embedded RP ranges: No additional configuration is required on other PIMv6 routers. The other routers discover the RP address from the IPv6 group address. For these routers to select a static RP instead of the embedded RP, the specific embedded RP group range must be configured in the access list of the static RP, and embedded RP support must be disabled.
