Abstract
The technology disclosed herein enables remote gateways to quickly re-learn MAC addresses of workloads for a gateway that has taken over for another gateway. In a particular embodiment, a method provides determining that a backup gateway should begin handling communications exchanged with one or more workloads of an active gateway for a logical network. The method further provides transferring a control message to one or more remote gateways in communication with the backup gateway. The control message instructs the remote gateways to change MAC addresses learned from, and associated with, the active gateway to being associated with the backup gateway. The method also provides, in the backup gateway, receiving network communications directed to one or more of the workloads from one or more of the remote gateways.
