1. A method for address resolution protocol (ARP) resolution over a link aggregation to a cluster of intermediary devices, the method comprising:

  • (a) establishing a link aggregation to a cluster of intermediary devices deployed between a plurality of a clients and a plurality of servers, the link aggregation comprising network interfaces to different intermediary devices in the cluster;

    (b) transmitting, by a first intermediary device of the cluster, an address resolution protocol (ARP) request on a network to resolve an internet protocol (IP) address;

    (c) transmitting, by the first intermediary device of the cluster, a message to each of a other intermediary device of the intermediary devices in the link aggregation to expect a reply to the ARP request from a device on the network corresponding to the IP address of the ARP request; and

    (d) receiving, by a second intermediary device of the intermediary devices in the cluster via the link aggregation, the reply to the ARP request from the device on the network corresponding to the IP address of the APR request.
