Abstract

One embodiment provides a system and method for managing, at a network node, a data structure indicating neighbor node address information. During operation, the system can determine, based on a media access control (MAC) address or an Internet protocol (IP) address associated with an entry in the data structure, a type of the entry, and set a timeout value for the entry based on the determined type. In response to detecting that an entry corresponding to the MAC address expires in a MAC table maintained by the network node, the system can identify an interface on the network node to which a neighbor associated with the MAC address was previously coupled and transmit a unicast neighbor-probe packet on the identified interface to determine a connection status of the neighbor.
