Tunnel interface view

setup-priority: Setup priority of the tunnel, in the range 0 to 7. A lower numerical 
number indicates a higher priority.

hold-priority: Holding priority of the tunnel, in the range 0 to 7. A lower numerical 
number indicates a higher priority. If not configured, it is the same as the setup 
priority.

Use the mpls te priority command to assign a setup priority and holding priority 
to the MPLS TE tunnel.

Use the undo mpls te priority command to restore the default.

By default, both setup and holding priorities of TE tunnels are 7.

To avoid flapping caused by improper preemptions between TE tunnels, the setup 
priority of an MPLS TE tunnel should not be set higher than its holding priority.

# Set the setup and holding priorities of TE tunnel 0 to 1.
