==Summary==
==Summary==
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.
This page is an overview of the VRRP section of {{{name}}} routers.

The <b>VRRP LAN configuration settings</b> section
The <b>VRRP LAN configuration settings</b> 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.

The <b>Check Internet connection</b> section
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.
Refer to the figure and table below for information on the fields contained in the Check Internet connection section.
