### Instruction:
What is the purpose of the MPLS traffic engineering fast reroute feature?
### Response:
The MPLS traffic engineering fast reroute (FRR) feature provides link and node protection for MPLS TE tunnels. It enables fast traffic recovery upon link or node failure using pre-signaled backup tunnels that bypass the protected resource. It is enabled on a per-tunnel basis with the tunnel mpls traffic-eng fast-reroute command.
