[c-nsp] IGMP disabled in VRFs on ASR9K

[John Neiberger]

I'm still in the middle of trying to get Multicast VPN Extranet
Routing to work and I've run into a weird problem. For testing, I have
a multicast source and a multicast receiver attached to the router.
When they're in the default VRF, the output of "show igmp interface"
shows that IGMP is enabled on those interfaces, as expected. When I
move them both into a different VRF, IGMP is disabled and I can't
figure out how to enable it. I even tried enabling PIM on g0/4/0/2 to
see if that would enable IGMP, but it still says it's disabled. Here's
my IGMP config:


router igmp
 vrf A
  interface Loopback98
   join-group 239.133.110.1 172.22.83.70
  !
  interface GigabitEthernet0/4/0/1
   version 3
  !
 !
 vrf B
  interface Loopback99
   join-group 239.133.110.1 172.22.83.70
  !
  interface GigabitEthernet0/0/0/3
   version 3
  !
  interface GigabitEthernet0/4/0/2
   version 3
  !
 !
!

But I still see this:


RP/0/RSP0/CPU0:lab-gw2#show igmp vrf A int
Fri Mar 11 21:37:36.335 UTC

Loopback98 is up, line protocol is up
  Internet address is 192.168.3.1/24
  IGMP is disabled on interface
GigabitEthernet0/4/0/1 is up, line protocol is up
  Internet address is 10.10.10.1/30
  IGMP is disabled on interface
RP/0/RSP0/CPU0:lab-gw2#show igmp vrf B int
Fri Mar 11 21:37:43.752 UTC

Loopback99 is up, line protocol is up
  Internet address is 192.168.1.1/24
  IGMP is disabled on interface
GigabitEthernet0/4/0/2 is up, line protocol is up
  Internet address is 172.22.148.17/27
  IGMP is disabled on interface
RP/0/RSP0/CPU0:lab-gw2#


What in the world is going on? Here is the rest of my config just in
case anyone spots anything wrong. I think we're tantalizing close to
getting this to work and it's really bugging me that I haven't been
able to figure it out.  lol
