FRAME-RELAY

Introduction

The following labs are to give you practice on configuring Frame Relay

to pass the CCIE labs successfully.

Equipment Required

The labs have been designed for ease of use and with the least amount

of equipment, without compromising the technicality of any of the labs.

The following equipment will be required to complete all the labs:

1 x Cisco Router with 4 port serial interface as the Frame Relay

Switch.

4 x 2621 with 1 Serial Interface

1 x Back-to-Back cable.

Ensure that the routers have at least the following code:

flash:c2600-ik9o3s3-mz.122-15.T5.bin

Practicing the labs

Just like the real exam, where each section is a small lab, these labs

have been designed as mini-labs in their own right. The labs have been

designed to cover the major areas of the syllabus to pass the CCIE lab

successfully.

To master the concepts, we would recommend the following approach:

Read through all the labs first

Attempt them once slowly and make sure your answers match with

that in the solution

Practice, Practice and Practice all the labs over again.

Highlight your weak areas, and then practice those labs again.

6.0 Frame Relay Traffic Shaping

1. You want to introduce QOS on your Frame-Relay Network. You want to do this

by prioritizing any routing protocol traffic over the frame-relay network

to high on Router1 frame-relay physical interface.

2. In order to traffic shape the network, you can configure the followingparameters:

a. CIR = 1544000

b. Bc = 8000

c. Be = 64000

3. Test your configuration to ensure that traffic shaping has been configured

appropriately on the physical interface of Router1

ATM

Introduction

The following labs are to give you practice on configuring ATM to pass

the CCIE labs successfully.

Equipment Required

The labs have been designed for ease of use and with the least amount

of equipment, without compromising the technicality of any of the labs.

The following equipment will be required to complete all the labs:

1 x ATM Lightstream Switch

2 x 2621 with ATM interfaces.

Ensure that the routers have at least the following code:

flash:c2600-ik9o3s3-mz.122-15.T5.bin

Practicing the labs

Just like the real exam, where each section is a small lab, these labs

have been designed as mini-labs in their own right. The labs have been

designed to cover the major areas of the syllabus to pass the CCIE lab

successfully.

To master the concepts, we would recommend the following approach:

Read through all the labs first

Attempt them once slowly and make sure your answers match with

that in the solution

Practice, Practice and Practice all the labs over again.

Highlight your weak areas, and then practice those labs again.


26/30


Lab Setup

In the ATM topology you have 2 ATM routers cabled via a Lightstream ATM

switch. 2 PVC are created on the switch to connect the two routers.

These VPI/VCI values are configured on the switch but are unknown to

you.

All the following lab scenarios are based on the following network

layout:

ATM-R1 ATM-R2


27/30


7.0 ATM Physical interfaces

1. Configure ATM-R1 and ATM-R2 for IP over ATM.

2. Ensure they do not use Inverse arp.

3. Test your configuration, by ensuring that they can ping each other.
