Running inter-as MP-BGP multicast between PE's using MDT under the VRF without a problem. Problem is GRE dynamic tunnel is built using my loopback interface in the global routing table and not in the VRF. All PIM/MSDP is done on loopback interface within the VRF between PE's so when i block AUTO-RP messages (126.96.36.199/188.8.131.52) between PE's, AUTO-RP messages is still exchange on loopback interface in the global since MDT is using that to build the GRE dynamic tunnel. Is it possible to be selective on which interface MDT uses to build dynamic GRE tunnel between PE's?
Is manual GRE tunnel the way forward?
Please let me know if you need clarification
