Learn how EIGRP makes IPv6 easier to deploy (2:59 min)
Enhanced Interior Gateway Routing Protocol (EIGRP) is a unique Cisco innovation. Highly valued for its ease of deployment and fast convergence, EIGRP is commonly used in many large Enterprise networks. EIGRP maintains all of the advantages of distance-vector protocols, while avoiding the concurrent disadvantages.
EIGRP is a simple protocol to understand and deploy. It's IPv6-ready, scales effectively in a well-designed network, and provides extremely quick convergence times. Other EIGRP advantages include:
EIGRP is an enhanced distance-vector protocol, relying on the Diffused Update Algorithm (DUAL) to calculate the shortest path to a network.
