Network requirements
In Figure 28, Device A and Device B are deployed for stateful failover in an enterprise network to provide
Internet access. They both run NAT to provide IP address translation.
It is required to:
• Configure the devices to back up each other, so that when one device fails, the other device takes
over the services to ensure service continuity.
• Enable automatic configuration synchronization from Device A (active device) to Device B (standby
device).
Configuration procedure
1. Configure Device A.
