Hands-on Lab
In this lab, we will take what we learned about configuring basic BGP
and add to it. We will configure RouterA as a route reflector, and we need
to configure the router's basic configuration as well. If you have forgotten
how to do this, refer to the Hands-on Lab section in Chapter 8, "Configur-
ing Basic BGP." Let's look at the graphic below to see the three routers in our
network. This graphic seems somewhat complex but is very easy to config-
ure step by step since it is only a small configuration with five routers. While
there is more than one way to configure the routers in the diagram below, I
will give a suggested configuration example based on the information from
Chapter 8 and this one.
Let's look at the lab objectives in the following list:
On each router, enable BGP with its autonomous system number
(ASN).
Identify the network each resides in.
