The question is often raised of how to provide a redundant network solution when connecting your leased cabinet or cage to your colocation’s network. This goal can be achieved in numerous ways but most solutions are fairly expensive. Below I list an entry level option to provide network redundancy when connecting to your colo. One of my preferred vendors is Fortinet because of cost and functionality. Most Foritnet devices will handle BGP, IPS, and provide seamless redundancy between devices. The solution below can be upgraded by purchasing more powerful devices as well as introducing a couple more devices into the solution.
