i have an MPLS backbone which is running sparse-mode. and i am trying to support Multicast for VRF's.. whats happening at the moment is when i configure MDT. The tunnels come up properlly. end to end ping works fine . but for only 1 icmp echo request. i get th response for first packet. after that packets aregetting dropped and i am getting no response.
any ideas ?
can i use SSM mode in conjunction with sparse-mode ?
