Abstract

A network fault detection apparatus, which detects L2 loops due to L3 bridge connections, is provided. A network fault detection apparatus acquires physical addresses corresponding to the network addresses of at least two nodes among the plurality of nodes constituting a network, and by detecting the existence of a plurality of physical addresses for network addresses of the two nodes, and detecting the existence of a physical address common to network addresses thereamong, detects an L2 loop caused by an L3 bridge connection, which induces a network fault.
