EIGRP Efficiency

Scaling EIGRP Neighbors in Hub-and-Spoke Networks

While many people count sheep to get to sleep, most network engineers find other things to count, such as IETF RFCs, and how many remote sites they can connect to a hub-and-spoke Enhanced Interior Gateway Routing Protocol (EIGRP) network. How many EIGRP neighbors can you have on a hub-and-spoke network? Looking at current best practices and testing can help answer the question.
