Abstract
A system and method routes data traffic over a unidirectional link of a computer network configured to implement a routing protocol, such as the ISIS routing protocol. To that end, the invention extends the ISIS routing protocol to allow dynamic discovery of neighboring routers (i.e., neighbors) that are connected via the unidirectional link and subsequent establishment of an adjacency between the neighbors over the link. Adjacency establishment is illustratively effected through the use of novel type/length/value (TLV) encoded formats appended to ISIS Hello packets to convey information between the neighbors.
