Hello,
In the following topology, I have created a TE tunnel from iosr1 to iosr10 through XR6, XR7 and Xr8. But the tunnel is down.
iosr1(gi0/1)---(gi0/0/0/1)XR6(gi0/0/0/0)---(gi0/0/0/0)Xr7(gi0/0/0/1)---(gi0/0/0/1)Xr8(gi0/0/0/0)---(gi0/0/0/0)iosr10

I am able to ping from 1.1.1.1 to 10.10.10.10.
I am not sure why the tunnel is down?
What 'show' commands should I use to debug such issues in the future.
Thanks,
Sachin
