Summary

Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol used for automatic default gateway selection for clients on a LAN network in case the main router (Master) becomes unavailable. Another VRRP router (Backup) then assumes the role of Master; thus backing up the connection.

This page is an overview of the VRRP section of {{{name}}} devices.

VRRP Configuration

The VRRP Configuration section lists VRRP instances currently existing on the device. By default the list is empty thus, you must first create at least one instance in order to begin configuring VRRP.

1. Enter a custom name for the new VRRP configuration in the 'Name' field.
2. Click the 'Add' button.
3. Click the 'Edit' button next to the newly created instance.

After clicking the 'Edit' button you should be redirected to that VRRP instance's configuration page, which should look similar to this:

Field	Value	Description
Enable	off | on; default: off	Turns VRRP on or off.
Virtualize MAC	off | on; default: off	Turns the possibility to use virtual MAC addresses on or off.
Virtual ID	integer [1..255]; default: 1	The Virtual Router Identifier (VRID) is a field in the VRRP packet IP header used to identify the virtual router in the VRRP cluster. Routers with identical IDs will be grouped in the same VRRP cluster.
Priority	integer [1..255]; default: 100	VRRP priority of the virtual router. Higher values equal higher priority. The router with the highest priority is considered to be the Master router while other routers are Backup routers. sends periodic VRRP Advertisement messages Master router - the first hop router in the VRRP cluster (i.e., the router that provides connectivity to LAN devices by default). Backup router - assumes the role of Master router in case it becomes unavailable. If there multiple Backup routers in the VRRP cluster, the one with the highest priority will assume the role of Master.
Interface	network interface; default: LAN	Selects which interface VRRP will operate on.
IP address	ip; default: none	Virtual IP address for the router's VRRP cluster.
