Abstract: In general, the disclosure relates to techniques for initiating a targeted LDP session in a manner that includes information specifying one or more application for which a targeted LDP session is being initiated. In one example, a method includes receiving, by a network device, a LDP initialization message to initiate an Label Distribution Protocol (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 LDP session is to be used for advertising forwarding equivalence class (FEC)-label bindings between the network device and the peer network device, and determining, by the network device, whether to allow the LDP session to be established based on the one or more applications specified in the TAC field.

Abstract: Problems associated with providing a large Clos network having at least one top of fabric (ToF) node, a plurality of internal nodes, and a plurality of leaf nodes may be solved by: (a) providing L2 tunnels between each of the leaf nodes of the Clos and one or more of the at least one ToF node to ensure a non-partitioned IGP L2 backbone, and (b) identifying the L2 tunnels as non-forwarding adjacencies in link state topology information stored in ToF node(s) and leaf node(s) such that the L2 tunnels are not used for forwarding traffic. Tunnel formation is prevented over L2.
