JunOS BGP

In this Tutorial We will be discussing how to setup an External Border Gateway Protocol (EBGP) between two routers.

Prerequisites

To complete this tutorial, you will need:

• A laptop running Linux or MacOS. for this tutorial I will be using a laptop running Ubuntu 16
• A console cable. Since all the new laptops today don't come with a USB port, you will need a USB to Console adapter
• The program "Screen"

If you don't have "screen" install it with the command below

sudo apt-get install screen

The Goal

Our goal is to setup the network like in the above image.

We have 2 offices. One in Texas and the other one in San Fransisco. Both offices have a Juniper MX80 router. The Texas router cr1-tx is in AS 17 and the San Fransico router cr1-sfo is in AS 29. We need to setup an External Border Gateway Protocol (EBGP) to connect both offices.
