Abstract
In general, techniques are described for distributing traffic engineering (TE) link information across network routing protocol domain boundaries using a routing protocol. In one example, a network device logically located within a first routing protocol domain includes a routing protocol module executing on a control unit to execute an exterior gateway routing protocol. The routing protocol module of the network device receives an exterior gateway routing protocol advertisement from a router logically located within a second routing protocol domain and decodes traffic engineering information for a traffic engineering link from the exterior gateway routing protocol advertisement. A path computation module of the network device computes a traffic engineered path by selecting the traffic engineering link for inclusion in the traffic engineered path based on the traffic engineering information.
