Configuring Adaptiveness to Dynamic Bypass LSPs

Dynamic Bypass LSPs are by default, adaptive in nature. To create a dynamic bypass LSP with a non-adaptive nature, use the adaptive command with the enable or disable option. Based on the value of the parameter, the command creates dynamic bypass LSPs as an adaptive bypass LSP or non-adaptive bypass LSP.

To enable adaptiveness to dynamic bypass LSPs, complete the following steps.

Enable the device for configuration.
```
device>configure
```
Enable the MPLS router.
```
device(config)# router mpls
```
Enable MPLS-capable interfaces and specify the selected Ethernet interface. In this example, the selected Ethernet interface is 2/8.
```
device(config-router-mpls)# mpls-interface ethernet 0/8
```

Enable the interface level dynamic bypass.

device(config-router-mpls-if-ethernet-0/8)# dynamic-bypass

Configure the adaptive command with the enable option to create an adaptive bypass LSP.
```
device(config-router-mpls-if-ethernet-0/8-dynamic-bypass)# adaptive enable  
```

The following example combines the steps above to create an adaptive bypass LSP,

device>configure
device(config)# router mpls
device(config-router-mpls)# mpls-interface ethernet 0/8
device(config-router-mpls-if-ethernet-0/8)# dynamic-bypass
device(config-router-mpls-if-ethernet-0/8-dynamic-bypass)# adaptive enable
