Abstract

An example network device includes a set of physical network interfaces and a control unit that executes a routing protocol and a traffic impact prediction module. The traffic impact prediction module determines, prior to occurrence of a topology-changing device fault, that one or more operating characteristics of the network device are indicative of a possible fault, wherein the network device is one of a plurality of network devices in a network, determines a probability of traffic loss associated with the possible fault, and determines an adjusted routing metric for routes impacted by the possible fault based at least in part on the probability of the traffic loss. The routing protocol sends, via at least one of the set of physical network interfaces, one or more interior gateway protocol update messages specifying the adjusted routing metric to at least one other network device in the network.
