Overview of policy-based routing (PBR) with two subnets for failover and redundancy

You can deploy policy-based routing (PBR) on two subnets serviced by their respective Exinda Appliances. The configuration detailed below reroutes traffic from one Exinda Appliance to another in case of hardware failure.

Policy-based routing with two subnets

• Request to access a location on the Internet is made on a client computer.
• The request is sent to the router, where the source destination is analyzed and compared to the policy configured on the router.
• Based on the results of the analysis, the request is either:

• sent to the Exinda appliance for optimization, and then back through the router to the requested destination.
• or, sent directly to the requested destination.
