Overview of virtual router redundancy protocol (VRRP) with policy-based routing (PBR) and VLANs

The VRRPVirtual Router Redundancy Protocol provides automatic assignment of IPInternet protocol routers, using virtual routers as proxies for physical routers. A virtual router with a static IP address acts as a gateway between the router and the Exinda Appliances. The VRRP receives traffic requests and distributes them to the appliances connected to it, providing greater reliability and steady traffic requests distribution.

A switch can be configured to act as a VLAN to group Exinda Appliances connected to different physical switches. This out-of-path deployment decreases latency and increases performance for networks with VLANs.

VRRP with PBR and VLANs

• The client computer requests access to a location on the Internet.
• 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:

• sent to the switch, which evenly distributes the traffic between the connected Exinda appliances, and then back through the router to the requested destination.
• sent directly to the requested destination.
