Abstract
According to one embodiment, a system includes a switch controller in communication with a plurality of switches in a switch cluster via a communication protocol, at least one switch in the switch cluster being configured to connect to a host, wherein the switch controller is configured to: maintain a Layer-3 (L3) host table configured to store entries including address information for hosts connected directly to the switch cluster, apply a policy to all existing entries in the L3 host table, and remove one or more existing entries according to the policy in order to reduce a number of entries in the L3 host table. In other embodiments, systems, computer program products, and methods for managing a L3 host table in software defined network (SDN)-based switch clusters having L3 distributed router functionality are presented.
