VPRN Features
the BGP updates message that carries this route the VRF route import extended community that
has the value of the c-multicast import RT of the VRF associated with the route, except if it is
known a priori that none of these addresses will act as multicast sources and/or RP, in which case
the (unicast) route need not carry the VRF Route Import extended community.
All c-multicast routes with the c-multicast import RT specific to the VRF must be accepted. In this
release, vrf-import and vrftraget policies don't apply to C-multicast routes.
The decision flow path is shown below.
if (route-type == c-mcast-route)
if (route_target_list includes C-multicast_Import_RT){
else
Run vrf_import and/or vrf-target;
