Overview
Using PBR, you can deploy your Exinda appliance in the network out-of-path but retain the in-path optimization capabilities. To achieve this, you should configure the router with the policy that determines whether the traffic is sent to the requested destination or the Exinda appliance.
This article explains the benefits offered by the Policy-Based Routing feature.
Information
- An Exinda appliance can be deployed physically out-of-path but logically in-path, which makes it useful in virtual environments, where an in-path deployment may be undesirable or impossible. The following are the benefits:
- Increased selectivity of the traffic to be optimized:
- For example, you can redirect all the web traffic to an Exinda appliance.
- Ability to configure an increased network topology:
- Depending on the router's capability, the traffic is redirected based on access-lists, which may use the port, source/destination address, etc.
- The following scenarios represent the common deployment topologies in which PBR can be used with an Exinda appliance:
- Basic Policy-Based Routing
- Configuring a Router for a Basic Policy-Based Routing Topology
