The '''Virtual Router Redundancy Protocol''' ('''VRRP''') is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the availability and reliability of routing paths via automatic default gateway selections on an IP sub-network. This chapter is an overview of the VRRP function in RUT routers.
The <b>Virtual Router Redundancy Protocol</b> (<b>VRRP</b>) 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.

The <b>Check Internet connection</b> section is used to set the parameters that define how the router will determine whether the Internet connection is still available or not. This is done by periodically sending ICMP packets to a defined host and awaiting responses. If no response is received after a defined period of time, the connection is determined to be down, and thus the role of Master is assumed by another router in the network.

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 and thus backing up the connection.

This chapter of the user manual provides an overview of the VRRP page for {{{name}}} devices.

VRRP configuration

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:Networking_{{{series}}}_manual_vrrp_vrrp_lan_configuration_settings_v2.png|border|class=tlt-border]]

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's LAN 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
