Abstract
A method for correlating routing errors to link failures in a network, the method including detecting a link failure between a first and a second router NODES in a network, associating a first node address indicated in a first routing table of the first router with a first partition of network, where a next hop of a packet destined for the first node address is the second router, associating a second node address indicated in a second routing table of the second router with a second partition of the network, where a next hop of a packet destined for the second node address is the first router, and correlating an error notification resulting from the failed delivery of a packet with the link failure where a source address of the packet corresponds to the first node address and a destination address of the packet corresponds to the second node address.
