EIGRP… The Basics

Enhanced Interior Gateway Routing Protocol (EIGRP) is an impressive set of features for IP Routing, which converges quickly and is on par and sometimes faster than OSPF. This routing protocol requires less processing time, less memory, and less network design than compared to OSPF. What’s the catch? This protocol is Cisco proprietary, if you have a network that uses non-Cisco routers, EIGRP will not and cannot be used on those routers. (Edit: Cisco has open this up to the IETF but you could still see issues if you found a vendor that supported EIGRP and not all features are supported***) EIGRP does not really fit into a specific spot of either Link-State or Distance vector, instead it stands on its own and is called hybrid routing protocol.
