Chapter 3. EIGRP Topology, Routes, and Convergence

This chapter covers the following subjects:

Building the EIGRP Topology Table: This section discusses how a router seeds its local EIGRP topology table, and how neighboring EIGRP routers exchange topology information.

Building the IP Routing Table: This section explains how routers use EIGRP topology data to choose the best routes to add to their local routing tables.

Optimizing EIGRP Convergence: This section examines the items that have an impact on how fast EIGRP converges for a given route.

EIGRP, like OSPF, uses three major branches of logic, each of which populates a different table. EIGRP begins by forming neighbor relationships and listing those relationships in the EIGRP neighbor table ...
