Abstract

See full text

A method and system are provided which facilitate synchronization of client IP binding databases across an extended network by leveraging the BGP control plane. During operation, a switch configures a first synchronization identifier indicating validated Internet Protocol (IP) binding information of an associated client. The switch receives a Border Gateway Protocol (BGP) update message associated with a first client, wherein the BGP update message includes a second synchronization identifier. Responsive to determining that the second synchronization identifier matches the first synchronization identifier, the switch: extracts from the BGP update message reachability information, which includes media access control (MAC) and IP information associated with the first client; validates the MAC and IP information based on security policies; and adds the MAC and IP information to a local IP binding database, thereby allowing synchronization of the validated IP binding information of the first client between the switch and other switches.
