Configuration > Networking > VRRP

This tab summarizes the configuration and state for appliances deployed with Virtual Router Redundancy Protocol (VRRP).

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

  • 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 in which no redundancy is needed.

  • 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.

VRRP Tab Settings

Field Description
Admin Options are up (enable) and down (disable).
Advertisement Timer Default is 1 second.
Group ID Value assigned to the two peers. Depending on the deployment, the group can consist of an appliance and a router (or L3 switch), or two appliances. The valid range is 1 to 255.
Interface Interface that VRRP is using for peering.
Segment Name of the segment, if enabled.
IP Address Owner An EdgeConnect appliance cannot use one of its own IP addresses as the VRRP IP, so this will always be No.
Master IP Current VRRP Master’s Interface or local IP address.
Master State Transitions Number of times the VRRP instance went from Master to Backup and vice versa. A high number of transitions indicates a problematic VRRP configuration or environment. In this case, check the configuration of all local appliances and routers, and then review the log files.
Preemption Leave this selected/enabled so that after a failure, the appliance with the highest priority comes back online and again assumes primary responsibility.
Priority The greater the number, the higher the priority. The appliance with the higher priority is the VRRP Master.
State Uptime Time elapsed since the VRRP instance entered the state it is in.
State The VRRP instance has three options:

Backup – Instance is in VRRP backup state.

Init – Instance is initializing, it is disabled, or the interface is down.

Master – Instance is the current VRRP master.
Virtual IP IP address of the VRRP instance. VRRP instances can run between two or more appliances, or an appliance and a router.
Virtual MAC address MAC Address that the VRRP instance is using. On an NX Appliance, this is in 00-00-5E-00-01-{VRID} format. On virtual appliances, the VRRP instance uses the interface’s assigned MAC Address (for example, the MAC address that the hypervisor assigned to wan0).
