VRRP resilience


Did you know providing media resilience to remote Industrial sites is easy?

Over the years remote access to unmanned sites has become critical for many businesses saving both time and money. Many of these sites are connected using broadband or mobile routers. Occasionally these services can fail.  So how can a remote access solution employ a backup channel?

VRRP (Virtual Router Redundancy Protocol) is the answer. A second router can be added to the network and VRRP handles the decision of which channel to use.

The big advantage that VRRP brings is that the connected equipment does not need to know there are 2 routers which share a single IP gateway address. The 2 or more routers decide which is the primary channel and data is routed via that channel until a failure occurs with the primary router whereupon the secondary backup router becomes the channel. Once the primary router is restored the data will switch back.
