Setting the From-Address for Dynamic Bypass LSPs

The user can configure an interface level from IP address when creating a dynamic bypass LSP for the protected MPLS interface . Use the dynamic bypasses from address as the IP address.

To set the from address for 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 interface. In this example, the selected Ethernet interface is 0/8.
```
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 from address. In this example, the from address configuration is 11.11.11.11.
```
device(config-router-mpls-if-ethernet-0/8-dynamic-bypass)# from 11.11.11.11
```

The following example combines the steps above to configure the from command IP address for dynamic bypass LSPs to 11.11.11.11.

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)# from 11.11.11.11
