MPLS local protection

MPLS Fast Reroute (also called MPLS local restoration or MPLS local protection) is a local restoration network resiliency mechanism. It is actually a feature of resource reservation protocol (RSVP) traffic engineering (RSVP-TE). In MPLS local protection each label switched path (LSP) passing through a facility is protected by a backup path which originates at the node immediately upstream to that facility.
