Abstract
One embodiment of a method includes receiving at a first network node traffic from a second network node; and sending by the first network node to a third network node information identifying the second network node via a Local Area Network (“LAN”) connection between the first and third network nodes. Subsequent to receipt of the information identifying the second network node, the third network node updates a locator table maintained by the third network node to include an entry including the information identifying the second network node received by the third network node from the first network node. Upon receipt by the third network node of a notification that the first network node has failed, the third network node sends an update only to network nodes that have an entry in the locator table indicating that the first network node has failed.
