Adaptive LSP configuration

Complete the following steps to configure an adaptive LSP.
  1. Configure the device.
    device# configure
  2. Enable the MPLS router.
    device(config)# router mpls
  3. Set the signaled label switched path (LSP).
    device(config-router-mpls)# lsp t1
  4. Set the egress router of the LSP.
    device(config-router-mpls-lsp-t1)# to 10.3.3.3
    In this example, the IP address of the egress router is 10.3.3.3.
  5. Set the ingress router of the LSP.
    device(config-router-mpls-lsp-t1)# from 10.2.2.2
    In this example, the IP address of the ingress router is 10.2.2.2.
  6. Set tie traffic engineering parameters mean rate in kbits. per second.
    device(config-router-mpls-lsp-t1)# traffic-eng mean-rate 1000
    In this example, the mean rate is set to 1000 kbits. per second.
  7. Enable the LSP to be modified without disabling the LSP.
    device(config-router-mpls-lsp-t1)# adaptive
  8. Set-up for fast reroute options.
    device(config-router-mpls-lsp-t1)# frr
  9. Exit the current mode.
    device(config-router-mpls-lsp-t1-frr)# exit

Example

The following example shows how to configure an LSP to be adaptive.

device# configure 
device(config)# router mpls
device(config-router-mpls)# lsp t1
device(config-router-mpls-lsp-t1)# to 10.3.3.3
device(config-router-mpls-lsp-t1)# from 10.2.2.2
device(config-router-mpls-lsp-t1)# traffic-eng mean-rate 1000
device(config-router-mpls-lsp-t1)# adaptive
device(config-router-mpls-lsp-t1)# frr
device(config-router-mpls-lsp-t1-frr)# exit
device(config-router-mpls-lsp-t1)# enable
