Today, even for small businesses, data and IT services must be cloud-ready and available at any time, from any location, by anyone. End-user appreciate (and increasingly, expect) of always-on business resources and non-disruptive operations. Improving data backup and recovery, and business continuity / disaster recovery are among top 10 IT priorities. As gateway is often the most vulnerable network element, this article focuses on an Internet protocol called VRRP (Virtual Router Redundancy Protocol) utilization as it enables the ability to have backup routers when using a statically configured router at some point of a local area network.
A redundant, cost-effective network block instead of one single router is presented, along with test topology and some guidelines. Test results are included and discussed.
