A method or corresponding apparatus in an exemplary embodiment of the present invention monitors an operational status of network links and retrieves or receives the operational status. The operational status is stored (e.g., within 50 msec) on an ongoing basis. The operational status corresponds to an operational LSP from among a primary LSP and secondary LSP(s) used to service traffic via the network links to maintain network connectivity via the LSPs. The secondary LSP(s) may be either a bypass LSP or a backup LSP, where each LSP is Fast Re-route (FRR) enabled. Further, correspondence between the primary LSP, secondary LSP(s), and the network links may be tracked. In order to deliver network traffic via the operational LSP known to service traffic between the source and destination, a link identifier may be used. The link identifier is determined from the source and destination information within the network traffic.
