How to Achieve IP Routing Redundancy
Redundancy is a critical aspect of every layer of today's modern IT infrastructure. Whether it's redundancy in server nodes, production environments, or backups, effective data security strategies begin with redundancy. This principle is no different within networks specifically related to IP routing redundancy. One of the most common strategies to maintain IP redundancy is through a First Hop Redundancy Protocol or FHRP. FHRP is a routing redundancy service that creates seamless fail-over capabilities at the first hop IP router.
At a high level, this strategy addresses the use case when a default gateway fails. Traditionally a default gateway can seem like a single point of failure as it manages all communication to the various subnets within a network. IP Routing Redundancy with FHRP creates redundancy such that, if the primary gateway server is lost, another router can act as the default gateway server in facilitating communication to the subnets. This strategy allows organizations to maintain uptime and meet critical business metrics in avoiding prolonged downtime with the loss of a default gateway server.
