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}}} routers.
The information in this page is updated in accordance with the [[Media:{{{fw_version}}}_single.bin|{{{fw_version}}}]] firmware version.
VRRP
To begin configuring VRRP you must first add a new VRRP configuration instance. You can do that by entering a custom name for the configuration and clicking the 'Add' button. A new VRRP configuration instance will appear in the "VRRP Configurations" list.
VRRP configuration
To begin configuring a VRRP instance, click the button that looks like a pencil next to it.
The VRRP LAN configuration settings section is used to set the main settings of VRRP. Refer to the figure and table below for information on the fields contained in that section.
[[File:{{{file_config}}}]]
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.
|
Interface | network interface; default: LAN | Selects which interface VRRP will operate on. |
IP address | ip; default: 192.168.1.253 | Virtual IP address for the router's VRRP cluster. |
