Hello Friends,

I am trying to configure MTR for multicast with ISIS in the lab. The topology is couple of CRS1's in the core and on the edge 7600(running 12.2 SRB1) and 12K (running IOS-XR).

Somehow I am not able to get the loopbacks of the 7600 advertised into the MTR multicast topology, however the same is advertised on regular ipv4 unicast ISIS.

Anyone experienced this, any thoughts.

TIA-Cheers,

Swaroop
