5.2.8 Virtual Router Redundancy Protocol (VRRP) Configuration

System Profile Configuration

A default gateway is a critical resource for connectivity. However, it’s prone to a single point of failure. Thus, redundancy for 
the default gateway is required by the access point. If WAN backhaul is available on an AP7131, and a router failure occurs, 
then the access point should act as a router and forward traffic on to its WAN link.

Define an external 

Virtual Router Redundancy Protocol

 (VRRP) configuration when router redundancy is required in a wireless 

network requiring high availability.

Central to the configuration of VRRP is the election of a VRRP master. A VRRP master (once elected) performs the following 
functions:

• Responds to ARP requests

• Forwards packets with a destination link layer MAC address equal to the virtual router MAC address

• Rejects packets addressed to the IP address associated with the virtual router, if it is not the IP address owner

• Accepts packets addressed to the IP address associated with the virtual router, if it is the IP address owner or accept 

mode is true

Those nodes that lose the election process enter a backup state. In the backup state they monitor the master for any failures, 
and in case of a failure one of the backups, in turn, becomes the master and assumes the management of the designated virtual 
IPs. A backup does not respond to an ARP request, and discards packets destined for a virtual IP resource.

To define the configuration of a VRRP group:

1. Select the 

Configuration

 tab from the Web UI.

2. Select 

Devices

.

3. Select 

System Profile 

from the options on left-hand side of the UI.

4. Select 

VRRP

.

NOTE: 

VRRP support is available only on AP7131 model access point, and is not 

available in other models.
