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

Looks like multicast is not enabled. 
Don't see the following in your config:

multicast-routing
 vrf multicast_test
  address-family ipv4
   interface all enable
  !

Vinod,

This is the error I get when trying to ping the multicast address under the
vrf:-

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?

Leigh

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??

Leigh
