ABSTRACT:
Techniques are described for fast reroute of traffic associated with a point to multi-point (P2MP) tunnel. A system may, for example, include a source network device and a plurality of destination network devices. The system further includes a label switched path (LSP) tunnel from the source network device to the plurality of destination network devices. The LSP tunnel includes a plurality of branch LSPs and may include one or more bypass tunnel associated with one or more of the branch LSPs. In other configurations, the system may include a second LSP tunnel from the source network device to the plurality of destination network devices. The second LSP tunnel includes a plurality of detour branch LSPs, and each of the detour branch LSPs corresponds to a respective one of the branch LSPs for the first P2MP LSP tunnel.
