Setting the reoptimizer-timer

When the user configures the re-optimization value to a non-zero value, in seconds, the reoptimizer-timer command enables the dynamic bypass LSP re-optimization.

The re-optimization timer value is configurable on all MPLS interface modes. The global set value is applicable to all dynamic bypass LSPs for which the corresponding interface level re-optimization timer value is not set.

To configure the reoptimizer-timer, complete the following steps.

Enable the device for configuration.
```
device>configure
```
Enable the MPLS router.
```
device(config)# router mpls
```

Enable dynamic bypass for configuration.

device(config-router-mpls)# dynamic-bypass

Configure the reoptimizer-timer. In this example, the reoptimizer-timer is configured to 300 seconds.
```
device(config-router-mpls-dynamic-bypass)# reoptimize-timer 300
```

Example

The following example combines the steps above to configure the reoptimizer-timer to 300 seconds.

device>configure
device(config)# router mpls
device(config-router-mpls)# dynamic-bypass
device(config-router-mpls-dynamic-bypass)# reoptimize-timer 300
