VRRP Template

Use this template to distribute common parameters for appliances deployed with Virtual Router Redundancy Protocol (VRRP).

In an out-of-path deployment, one method for redirecting traffic to the Silver Peak appliance is to configure VRRP on a common virtual interface. The possible scenarios are:

n	When no spare router port is available, a single appliance uses VRRP to peer with a router (or Layer 3 switch). This is appropriate for an out-of-path deployment where no redundancy is needed.

n	A pair of active, redundant appliances use VRRP to share a common, virtual IP address at their site. This deployment assigns one appliance a higher priority than the other, thereby making it the Master appliance, and the other, the Backup.

Definitions (alphabetically)

n	Admin = The options are up (enable) and down (disable).

n	Advertisement Timer = default is 1 second.

n	Authentication String = Clear text password for authenticating group members.

n	Preemption. Leave this selected/enabled so that after a failure, the appliance with the highest priority comes back online and again assumes primary responsibility.

n	Priority. The greater the number, the higher the priority. The appliance with the higher priority is the VRRP Master.
