Configuring bypass LSP from address

The user can configure a bypass LSP with an optional from IPv4 address. When configuring, use this IP address as a from IP address in the RSVP session. The from address is an adaptive parameter.

To configure a bypass LSP from address, complete the following steps.

  1. Enable the device for configuration.
    device>configure
  2. Enable the MPLS router.
    device(config)# router mpls
  3. Configure the bypass LSP with the unique static bypass LSP name of my-bypass-lsp .
    device(config-router-mpls)# bypass-lsp my-bypass-lsp
  4. Configure the bypass LSP from address.
    device(config-router-mpls-bypass-lsp-my-bypass-lsp)# from 10.20.1.10
    In this scenario, the selected from address is 10.20.1.10 .

The following example combines the steps above to configure a static bypass LSP with a unique bypass LSP name of my-bypass-lsp and an IPv4 from address of 10.20.1.20 .

device>configure
device(config)# router mpls
device(config-router-mpls)# bypass-lsp my-bypass-lsp
device(config-router-mpls-bypass-lsp-my-bypass-lsp)# from 10.20.1.10
