Enabling TE FRR

TE FRR must be enabled for a primary tunnel before a bypass tunnel is established.

Perform the following configurations on the ingress node of an MPLS TE tunnel.

Run system-view
The system view is displayed.
Run interface tunnel tunnel-number
The interface view of a primary tunnel is displayed.
Run mpls te fast-reroute [ bandwidth ]
TE FRR is enabled.

Only the primary tunnel in a tunnel protection group can be configured together with TE FRR on the ingress node. Neither the protection tunnel nor the tunnel protection group itself can be used together with TE FRR. If the tunnel protection group and TE FRR are used, neither of them takes effect.

For example, Tunnel1 and Tunnel2 are tunnel interfaces on MPLS TE tunnels and the tunnel named Tunnel2 has a tunnel ID of 200. The mpls te protection tunnel 200 and mpls te fast-reroute commands cannot be configured simultaneously on Tunnel1. That is, the tunnel protection group and TE FRR cannot be used together on Tunnel1. A configuration failure will occur if the mpls te protection tunnel 200 command is run on Tunnel1 and the mpls te fast-reroute command is run on Tunnel2.
Run mpls te commit
The configuration is committed.
