Template:Networking rut manual vrrp

Summary

The 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}}}_WEBUI.bin|{{{fw_version}}}]] firmware version.

Field	Value	Description
Enable	yes | no; default: no	Turns VRRP on or off.
IP address	ip; default: 192.168.1.253	Virtual IP address for the router LAN's VRRP cluster.
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.
Advertisement Interval	integer [1..255]; default: 1	Time interval in seconds between advertisements
