Abstract:
A label switching router (LSR) and a method of switching data traffic to a predefined backup traffic path by the LSR in an MPLS (multi-protocol label switching) network. The LSR, upon detection of failure of a protected path during an LDP session, maintains an LDP session and forwards data traffic via the backup traffic path according to a forwarding table. The forwarding table contains logical output interface information including an outgoing label, a logical output interface, and the next hop of the predefined backup path.
