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.
