[c-nsp] Multicasting with MDT between ASR9K and ME3600

Hello all,
Thanks for the responses. I didn't put the mdt config snippet in there, but it has been configured and is peered up just right.
>From the 3600, I have three tunnels dynamically created:
Tunnel 0 is created with reference to the default/global pim peer
Tunnel 1 is created with reference to the mdt when configured under the vrf
Tunnel 2 is created with reference to the rp under the vrf, I have to statically assign this.
The 9K and the 3600 can see each other in the vrf, but I can't long a test group of 239.0.1.239 that I put onto the loopbacks of both the 9K and the 3600. Oddly, the 9K complains about a process not being available when I try to ping the multicast address.
The default pim is created and all devices respond no problem, all bgp is built and the mdt address family is active all over.
Am I missing something obvious or is there something more sinister afoot?

Subject: [c-nsp] Multicasting with MDT between ASR9K and ME3600
Hello folks,
We're going through setting up multicasting in our network between some core ASR9K's and some edge ME3600's. The underlying multicasting is implemented and working well, but we're having some trouble in getting the vrf's working correctly for multicasting. Would someone be able to offer some sagely advice and some pointers as to what we're doing wrong or not doing??
