The mpls te reoptimization command immediately triggers re-optimization for an MPLS TE tunnel.
| Parameter | Description | Value |
|---|---|---|
| tunnel interface-number | Specifies a tunnel that needs immediate re-optimization. | - |
Usage Scenario
After the network topology is modified manually, a new optimal path will be calculated. The new optimal path needs to be immediately used by the TE tunnel.
TE tunnels need to be immediately optimized in batches, optimizing resources of these TE tunnels in time.
If you run the mpls te reoptimization command without specifying the tunnel interface-number parameter, all TE tunnels are optimized. If you run the mpls te reoptimization command and specify the tunnel interface-number parameter, the specified TE tunnels are optimized.
Automatic re-optimization: means that the TE tunnel is periodically optimized, saving manpower. To enable automatic re-optimization, run the mpls te reoptimization (tunnel interface view) command in the tunnel interface view. In addition, this command takes effect only on an established TE tunnel.
Manual re-optimization: means that the TE tunnel is immediately optimized. To immediately optimize the TE tunnel, run the mpls te reoptimization command in the user view.
Precautions
If the re-optimization function is configured after an explicit path is configured and a new path fails to meet the explicit path constraints, the re-optimization function will not take effect.
After a TE tunnel is configured with the re-optimization function, the tie-breaking in most-fill mode will not be supported.
The mpls te reoptimization command cannot be run together with the following commands:
