Stumped. What do you check for if you know your config is correct. The rp mappings come through. The "sh ip mroute" verifies the routes. The tunnels are up. All looks good but you cannot ping!?
ip vrf test
route-target import 1:1
route-target export 1:1
mdt default 188.8.131.52
ip multicast routing vrf test
ip pim vrf test rp-address 192.168.0.1
ip add 192.168.2.2 255.255.255.0
ip vrf forwarding test
ip pim sparse-mode
Just the ip addresses change per PE device.
