Build a Network Challenge 2 - BGP

Purpose:

In this lab, we add upon our environment from Challenge 1 by using BGP in order to extend network connectivity to a Partner and Customer Network.

Materials:

• Cisco Packet Tracer
• Completed Challenge 1 Packet Tracer File

Objective:

The completed lab environment should look similar to below:
