Hi,
I have an environment where you have a ME3800 and an ASR9000 as PEs for mVPN.
Within the VPN the control and data plane for ipv4 works just fine. That is I can ping from a loopback on ME3800 to the 9000 (both on a VRF).
regarding the core and mVPN i'm using SSM/MDT and the control plane seems to be happy. even the tunnel interface is up on the ME3800 for traffic within the mVPN. within the mVPN i'm using BSR (ASR9k=RP and ME3800 knows about it).
I have a loopback on ME3800 which i can multicast-ping, via an igmp join. I have the same setup on the ASR, but i cannot simulate to the join on the loopback no the ASR from either the ME3800 nor the ASR.

RP/0/RSP0/CPU0:ASR_TEST#
now, AFAICT,control plane i correct, so I tried the ASR9k which is the BSR and RP within the vrf and when pinging the local multicast group (225.0.0.2) from the ASR9k I get:
RP/0/RSP0/CPU0:ASR_TEST#ping vrf mcast 225.0.0.2
Thu Jun 20 17:56:08.714 CST
Mdef cons get failed for VRF 0x60000001 - No such process
RP/0/RSP0/CPU0:ASR_TEST#
Basically my only question is: has anybody seen this error message? The most basic test for me would be to join a group in my own RP and try to ping it locally on the VRF, but this doesn't work. Any ideas?
TIA,
c.
