EIGRP Tutorial

In this tutorial, we are going to set up a simple EIGRP routed network.
The scenario will illustrate how you would deploy a EIGRP routed network on a hub & spoke designed WAN network. The following is a diagram illustrating how to connect four routers over a EIGRP routed WAN.

Each router has one directly connected ethernet LAN segment. Once the circuits are connected, & the serial & ethernet interfaces are configured, we will enable EIGRP routing. The following shows each routers EIGRP configuration:

Each router has one or more directly connected networks, that either a serial
or ethernet interface directly connect to. For each directly connected network,
you need to make sure the EIGRP network statement(s) encompass that network.
This will make sure the network is advertised to the router's other EIGRP neighbors & allow the protocol to send hellos out that interface to form
EIGRP neighborships.
