Patent ID: 8243587

Claim:
A method, comprising: determining, upon initiation of an interior gateway protocol (IGP) at a network device, that a label distribution protocol (LDP) session is not associated with the network device, wherein the network device is included in a targeted LDP (tLDP) session; configuring IGP metric information, for both a physical interface and a forwarding adjacency label switched path (FA-LSP) associated with the network device and the tLDP session, to maximum values available based on the IGP associated with a distance-vector type or a link-state type routing protocol used by the network device, to each indicate a high cost corresponding to a time period related to relative setup times for the IGP and the LDP session; and transmitting the configured metric information to other network devices, in a network that includes the FA-LSP and the tLDP session, to inhibit, for the time period, selection of the tLDP session by the other network devices when routing data through the network.
