About Multicast VRF-Lite Route Leaking
Beginning with Cisco NX-OS Release 7.0(3)I7(1), multicast receivers can forward IPv4 traffic across VRFs. In the previous releases, multicast traffic could flow within the same VRF.
With multicast VRF-lit route leaking, Reverse Path Forwarding (RPF) lookup for multicast routes in the receiver VRF can be performed in the source VRF. Therefore, traffic originating from the source VRF can be forwarded to the receiver VRF.
When a route processor reloads, multicast traffic across VRFs behaves the same as traffic forwarded within the same VRF.
To support RPF selection in a different VRF, use the ip multicast rpf select vrf command.
