Abstract:
1. An apparatus, comprising: one or more processors; first logic encoded in one or more tangible media for execution and when executed operable for discovering, without prior knowledge of an existence of tunnels in a data communications network and without prior knowledge of a topology of the data communications network, whether for a pair of nodes in the data communication network one or more configured tunnels have been already established, and remotely accessing each node in a plurality of nodes in the data communications network; second logic which when executed is operable to identify, for every accessed node of the plurality of nodes, whether a tunnel is configured on the accessed node; and third logic which when executed is operable, when the identified tunnel is configured on the accessed node, to determine whether the identified tunnel is a load balancing tunnel, and in response to determining that the identified tunnel is not a load balancing tunnel, determining whether the identified tunnel is a backup-path-fast-reroute tunnel, and whether the identified tunnel has a fault.
