Setting up Fast-Reroute Protection for an LSP

To create a protected LSP, do the following:

Create the LSP as described in Creating or Deleting an RSVP-TE LSP.
Enable the fast-reroute feature on the LSP using the following command: configure mpls rsvp-te lsp lsp_namefast-reroute [enable | disable]
Create a path for the LSP as described in Creating an RSVP-TE Path.
Define the path route as described in .
If you want to use a custom profile instead of the default profile, create a profile for the protected LSP as described in Creating and Deleting an RSVP-TE Profile.
If you want to configure the custom profile created in the previous step, configure the profile as described in Configuring an RSVP-TE Profile.
If you want to use a custom fast-reroute profile instead of using the default fast-reroute profile, create the profile using the following command at the ingress LER:
create mpls rsvp-te profile profile_namefast-reroute
If you want to configure the custom fast-reroute profile created in the previous step, use the following command at the ingress LER:
configure mpls rsvp-te profile frr_profile_name {bandwidthbandwidth_rate_bpsbandwidth_rate_unit} {detour {hop-limithop_limit_value} {bandwidth-protection [enabled | disabled]} {node-protection [enabled | disabled]}} {hold-priorityhold_priority_value} {setup-prioritysetup_priority_value}
Add the path to the protected LSP and select the standard and fast-reroute profiles using the following command:
configure mpls rsvp-te lsp lsp_nameaddpath [path_name | any] {profileprofile_name} {primary {frr_profile_name} | secondary}
