The February IP Corner article Small Site Multi-Homing described how to implement the small site multi-homing with existing Cisco technologies in the existing ISP environment. That article has generated lots of responses, most of them being questions about redundant implementation of the same principles. Therefore Ivan Pepelnjak decided to describe how to extend the small site multi-homing design with a set of redundant routers. The final design still retains the administrative simplicity of the original solution – with no need to own public IP address space, autonomous system number or to run Border Gateway Protocol (BGP).
