Configuring Traffic Forwarding; Configuration Prerequisites; Configuration Procedures - H3C SR8800 10G Mpls Configuration Manual

Step
1. Enter system view.
2. Enter MPLS TE tunnel interface
view.
3. Configure maximum number
of tunnel setup retries.
4. Configure the tunnel setup
retry interval.
5. Submit current tunnel
configuration.
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
should not be set higher than its holding priority.
To assign priorities to a tunnel:
Step
1. Enter system view.
2. Enter MPLS TE tunnel interface
view.
3. Assign priorities to the tunnel.
4. Submit current tunnel
configuration.
