A. Fast Reroute is a mechanism that facilitates fast local repair of LSPs, in case of link or node failures. It extends RSVP to request link or node protection by appending a Fast Reroute object in the Path message, which indicates to downstream LSRs that a locally generated backup LSP should be setup to back up this Protected LSP, in case the downstream link or node fails.
