3. Enable the system to record
routes or labels when setting
up the tunnel.
• Record routes:
mpls te record-route
• Record routes and labels:
mpls te record-route label
Use either command.
Both route recording and label
recording are disabled by default.
The mpls te record-route label
command is not supported when
the signaling protocol is CR-LDP.

Configuring tunnel setup retry
You can configure the system to attempt setting up a tunnel multiple times until it is established
successfully or until the number of attempts reaches the upper limit.

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.
