Introduction
---------------------------------------------------------------------------------------------------------
Enhanced Interior Gateway Routing Protocol (EIGRP) is an interior gateway protocol suited for many different topologies and media. In a well designed network, EIGRP scales well and provides extremely quick convergence times with minimal network traffic.
EIGRP Theory of Operation
-----------------------------------------------------------------------------------------------------------
Some of the many advantages of EIGRP are:
very low usage of network resources during normal operation; only hello packets are transmitted on a stable network
when a change occurs, only routing table changes are propagated, not the entire routing table; this reduces the load the routing protocol itself places on the network.
rapid convergence times for changes in the network topology (in some situations convergence can be almost instantaneous)
EIGRP is an enhanced distance vector protocol, relying on the Diffused Update Algorithm (DUAL) to calculate the shortest path to a destination within a network.
