Configuring EIGRP
Enhanced IGRP (EIGRP) is a Cisco proprietary enhanced version of the IGRP. EIGRP uses the same
distance vector algorithm and distance information as IGRP; however, the convergence properties and
the operating efficiency of EIGRP are significantly improved.
distance vector algorithm and distance information as IGRP; however, the convergence properties and
the operating efficiency of EIGRP are significantly improved.
The convergence technology employs an algorithm referred to as the Diffusing Update Algorithm
(DUAL), which guarantees loop-free operation at every instant throughout a route computation and
allows all devices involved in a topology change to synchronize at the same time. Routers that are not
affected by topology changes are not involved in recomputations.
