Abstract
Techniques are described for providing fast reroute intra-area node protection for label switched paths (LSPs) using label distribution protocol (LDP). In one example, a network device may be configured to use network topology information, obtained by an Interior Gateway Protocol (IGP) executing on the network device, to identify a next next hop merge point to which to automatically establish a bypass LSP, and to which to establish a targeted LDP session for obtaining a label advertised by the next next hop merge point.
