Assigning priorities to a tunnel
Two priorities, setup priority and holding priority, are assigned to paths for MPLS TE to make preemption
decision. For a new path to preempt an existing path, the setup priority of the new path must be greater
than the holding priority of the existing path.
To avoid flapping caused by improper preemptions between CR-LSPs, the setup priority of a CR-LSP must
not be set higher than its holding priority.
Follow these steps to assign priorities to a tunnel:
To do… Use the command... Remarks
Enter system view system-view ––
Enter MPLS TE tunnel interface view interface tunnel tunnel-number ––
Assign priorities to the tunnel

[ hold-priority ]
Optional
The default setup and holding
priorities are 7.
