EIGRP -- replaced by new EIGRP edition Enhanced Interior Gateway Routing Protocol (EIGRP) bears almost no resemblance to its predecessor (IGRP), beyond the configuration commands. EIGRP is a completely new protocol. It successfully addresses most network scalability needs, while remaining (relatively) simple to set up and maintain. EIGRP is an advanced distance-vector protocol, meaning it makes decisions based on metric information it receives from its neighbors. However it employs some of the advanced mechanisms of the link-state protocols. It establishes neighbor relationships with adjacent routers, it sends only changes in its updates, and it keeps a topology database.
