ESTRUCTURA DEL UNIVERSO Y

J. A. Rubiño

Before You Begin

Please look at the provided diagrams and read through the whole lab before you start. Read the directions very carefully to make sure you are doing what is being asked of you. This is very important when you take Cisco’s CCIE lab.

Each section contains a small diagram that is designed to show you the focus of where the issue is.

Multiple topology diagrams are available for this lab, including an IPv4 and a BGP diagram.

General Rules

You may modify, but not delete or remove any prefix-lists, route-maps, or access-lists.

Do not modify any IP addressing on any interfaces.

The BB routers are not accessible.

All routers have an interface loopback 0 with the address 10.x.x.x, where x is the router number.

ISP routers have a loopback address of 10.10x.10x.10x. BB routers have a loopback address of 100.x.x.x .Switches have loopback addresses of 172.xx.xx.xx.

MPLS routers have a loopback address of 10.x.x.x /32.

Static/default routes are NOT allowed unless otherwise stated in the task.

Save your configurations often.

Estimated Time to Complete: 2 hours

Pre-Setup

Please login to your vRack and load the initial Configuration. This lab is intended to be used with

online rack access. Connect to the terminal server and complete the troubleshooting tasks as

detailed below.
