Summary

EIGRP is Cisco Systems, Inc. proprietary and is one of the most feature-rich and vigorous routing protocols developed and used today. EIGRP's combination of features blends the best attributes of distance vector protocols with the best attributes of link-state protocols. The result is a hybrid routing protocol that defies easy categorization with conventional protocols, such as BGP or OSPF.

EIGRP is easy to configure, enabling efficient operation in the support of IP(v4), AppleTalk, and IPX routed protocol traffic.
