Abstract
The present technology carries a calculated hash value from a standby node to an active node in an HA cluster when the packet is redirected to the active node. The hash value calculated at the standby node can be placed in the peer divert header during inner Layer 3 processing and carried to the active node in a local data bus or data line. The active node can then decode the hash value received from the standby node using the divert header. In doing so, security is preserved for the transmitted packet, but the active node can also load balance the packet based on the hash value calculated by the standby node.
