Dive into Cisco's advanced distance-vector routing protocol, EIGRP. This module covers the core mechanics of the Diffusing Update Algorithm (DUAL), neighbor discovery, Reliable Transport Protocol (RTP), and the critical concept of Feasible Successors for sub-second convergence. You will also master the art and danger of route redistribution, learning how to safely leak routes between EIGRP, OSPF, and BGP without causing routing loops or suboptimal path selection. Perfect for network engineers preparing for CCNA or CCNP Enterprise certifications.
