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.

VRRP configuration

The VRRP LAN configuration settings section

[[File:{{{file_config}}}]]

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.

Check Internet connection

The Check Internet connection section
