Abstract
The technology disclosed herein enables high availability bridging between Layer 2 (L2) networks. In a particular embodiment, a method includes high availability bridge cluster comprising a first bridge node and a second bridge node. The first and second bridge nodes include first and second active bridges and first and second standby bridges, respectively. The method provides, in the first active bridge, bridging network communications between two or more L2 networks. The second standby bridge acts as a failover bridge for the first active bridge. The method further provides generating a failure detection message that incorporates a hardware address of the first bridge node and transferring the failure detection message from the first bridge node to the second bridge node. In the second standby bridge, the method provides receiving the failure detection message and using the hardware address to synchronize bridging information between the first active bridge and the second standby bridge.
