Abstract
A method for use in a network, including: receiving network traffic at a redundant gateway device established according to a redundant gateway protocol; forwarding known unicast traffic received at the redundant gateway device from the redundant gateway device to a tunnel endpoint through a tunnel established according to a tunneling protocol; forwarding broadcast, unknown unicast, and multicast traffic to the tunnel endpoint through the tunnel if the redundant gateway device is a master gateway under the redundant gateway protocol; and dropping the broadcast, unknown unicast, and multicast traffic if the redundant gateway device is a backup gateway under the redundant gateway protocol.
