[c-nsp] ASR9000 Multicast over P2MP TE tunnels

Hello experts.

I'm trying to map multicast traffic to RSVP-TE tunnel, without success. I'm
not quite sure what I might be missing (I think it's all there).

Topology is simple:


155.1.1.0/24------Gi0/0/0/0.110----XR1--------MPLS----------XR2-------Gi0/0/0/0.150


Here's the config (the relevant stuff - there's whole RSVP-TE topology
already working under it):

HEADEND (asr9k)
---------------------------

interface tunnel-mte1000
 ipv4 unnumbered Loopback0
 load-interval 30
 destination 2.2.2.2
  path-option 10 dynamic
 !
 destination 3.3.3.3
  path-option 10 dynamic
 !
 path-selection metric igp
 affinity ignore
!

multicast-routing
 address-family ipv4
  interface tunnel-mte1000
   enable

router igmp
 interface tunnel-mte1000
  static-group 232.11.11.11 155.1.1.104
 !

TAILEND (asr9k)
-------------------------

multicast-routing
 address-family ipv4
  core-tree-protocol rsvp-te group-list acl-232
 static-rpf 155.1.1.104 32 mpls 1.1.1.1

router igmp
 interface GigabitEthernet0/0/0/0.150
  static-group 232.11.11.11 155.1.1.104


Tunnel is up, I'm trying to ping from 155.1.1.104 which is connected
directly to HEADEND router.

show mrib route 232.11.11.11 | begin \\(

*  Outgoing Interface List*
*    tunnel-mte1000 Flags: F NS LI LVIF, Up: 01:18:30*

However, no traffic seems to pass trough tunnel.

*show mfib interface tunnel-mte 1000*

*Interface : tunnel-mte1000 (Enabled)*
*SW Mcast pkts in : 0, SW Mcast pkts out : 0*
*TTL Threshold : 0*
*Ref Count : 5*


Any chance you could give me a pointer to where I might be wrong? As a side
note, I don't see LSP-VIF interface coming up on tailend router.

Best Regards!
