To check the packet counters, use show ip mroute vrf vrf_name count command:

Router# show ip mroute vrf blue count

You can configure MLDP MVPN for extranet services using these methods:

Source-Side Chaining (SSC): Configure the phantom receiver MVRF on the source-side router. 
Multicast routes with VRF Reverse Path Forwarding (RPF) loopup should be configured on the 
source PE.

Receiver-Side Chaining (RSC): Configure the phantom source MVRF on the receiver-side router. 
Multicast routes with VRF RPF loopup should be configured on the receiver VRF.
