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.
