Hi,

the PCALC error is telling you the reason why the Tunnel is not up.

Check with "show mpls traffic-eng topology 10.x.40.92". 

Most reasonable cause of this failure is that you do not have mpls end-to-end enabled (MPLS TE, RSVP etc).

Just check your configuration.

I found it. Before I posted here, I changed the system IP of Nokia. However, when I show mpls traffic-eng topology, ASR9k still saw the old address. I tried to reload Nokia box, it's solved, the tunnel came up.

Thank you very much.
