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 {bandwidth
bandwidth_rate_bpsbandwidth_rate_unit} {detour {hop-limit
hop_limit_value} {bandwidth-protection [enabled | disabled]} {node-protection [enabled | disabled]}} {hold-priority
hold_priority_value} {setup-priority
setup_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_name
add
path [path_name | any] {profile
profile_name} {primary {frr_profile_name} | secondary}
