Claim:
1. A method comprising: receiving, by a network device, a Label Distribution Protocol (LDP) initialization message to initiate a targeted LDP session with a peer network device, the LDP initialization message including a Targeted Applications Capability (TAC) field specifying one or more applications for which the targeted LDP session is to be used for advertising forwarding equivalence class (FEC)-label bindings between the network device and the peer network device; determining, by the network device, whether to allow the targeted LDP session to be established based on the one or more applications specified in the TAC field and based on whether a pre-configured maximum number of LDP sessions for the one or more applications specified in the TAC field has been reached; and in response to determining the targeted LDP session is allowed to be established, automatically establishing, by the network device, the targeted LDP session with the peer network device, wherein the peer network device is not a neighbor router to the network device.
