Abstract
In one example, a merge point network device (MP) receives a plurality of resource reservation request messages for establishing a plurality of label switched paths (LSPs), wherein each of the plurality of LSPs has a common point of local repair network device (PLR) and has the MP as a common MP, wherein each of the resource reservation request messages identifies a common bypass tunnel that extends between the PLR and the MP and avoids a protected resource. The MP stores an association between the bypass tunnel and each of the plurality of LSPs. The MP receives a single message to trigger creation at the merge point network device of backup LSP state information for all of the plurality of LSPs. In response to receiving the single message, the MP installs state information for all of the LSPs that correspond to the bypass tunnel according to the stored association.
