Enhanced Interior Gateway Routing Protocol (EIGRP) was introduced as a distance-vector routing protocol in 1992. It was originally designed to work as a Cisco proprietary protocol on Cisco devices only. In 2013, Enhanced Interior Gateway Routing Protocol became a multi-vendor routing protocol.
Enhanced Interior Gateway Routing Protocol is an advanced version of IGRP that lets routers exchange information more efficiently than then previous network protocols. As the name suggested, Enhanced Interior Gateway Routing Protocol is an enhancement of IGRP(Interior Gateway Routing Protocol). IGRP is obsolete since IOS 12.3 release. It was a classful, distance vector routing protocol.
Enhanced Interior Gateway Routing Protocol is a distance vector routing protocol with features of link-state routing protocols. It is suitable for many different topologies and media. In a well-designed network, Enhanced Interior Gateway Routing Protocol can scale to include multiple topologies and can provide extremely quick convergence times with minimal network traffic........Read More
