VRRP – What is this?
Virtual Router Redundancy Protocol ( VRRP) is a computer networking protocol, providing automatic failover functionality in case one of multiple router interfaces (or the entire router) breaks/fails. You could say that two physical routers
VRRP is the perfect solution to increase uptime of your network.

The most important features of VRRP are:
VRRP gives you real-time status updates of your router
So, no information about routings
Every VRRP instance can only work on 1 subnet
Multiple VRRP instances are possible to implement multiple redundant subnets
WAN gateway doesn’t change
Works with ethernet and MPLS networks
Why is VRRP relevant for your business?
The Virtual Router Redundancy Protocol (VRRP) is used to realize failover functionality. For your business, this means:
Automatic back-up; two physical routers appear as one virtual router
High reliability of connection and hardware (CPE)
One gateway and IP address; simple configuration by IT VRRP in your business
When is VRRP useful? Below you can find several situations in which VRRP was useful:
Fibercut; A broken fiber can happen to any company. For example, during construction nearby where an excavator accidentally cuts the cable. In our experience, fixing this takes more than eight hours..
Router failure; Routers almost always work. However, if they fail, for example when the power supply dies, consequences are huge.
