Summary[edit source]

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 and thus backing up the connection.

This chapter of the user manual provides an overview of the VRRP page for RUT900 devices.

VRRP configuration[edit source]

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.

Field Value Description
Enable yes | no; default: no Turns VRRP on or off.
Virtualize MAC yes | no; default: none 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.
Advertisement Interval integer [1..255]; default: 1 Time interval in seconds between advertisements
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.
