This document is a student lab manual for configuring Huawei routers. It provides instructions for 6 experiments: 1) Introduction to Huawei routers, which demonstrates configuring IP addresses on router interfaces and PCs to enable communication; 2) PAP authentication protocol, which configures PAP authentication between two routers; 3) Frame Relay Protocol; 4) CHAP authentication protocol; 5) X.25; and 6) Frame Relay Sub-interfaces. The introduction experiment provides a baseline for the other experiments by demonstrating basic router and IP address configuration. The PAP, CHAP, and other experiments build on this by adding different WAN protocols and authentication methods.

Explanation of this Manual
Attention please: when you log on the computer for LAB 3, make sure
you ask the tutor to configure the cables for you, do not do it
yourself!!!
(1) We only prepare the manuals for compulsory labs, yet if you still have extra
time, please get the manuals for other labs from the tutors.
(2) Lab 3.2 and 3.3 are compulsory. The tutor will introduce 3.1, which is the
basic lab of this manual. Remember the commands of the lab; try to answer the
question asked. This will give you useful practice for the end of semester lab test.
(3) Lab 3.4, 3.5 and 3.6 are optional.
For this experiment you will need to work in pairs. The first pair will use PCs 1
and 2, second pair PCs 3 and 4, third pair PCs 5 and 6, and the fourth pair PCs 7
and 8.
Before you telnet into the router you need to configure an IP address, subnet
mask and default gateway for your PC.
If you are using PC 1, 3, 5 or 7 configure the following:
1. IP address of PC - 10.128.0.2, subnet mask – 255.255.255.0, and default
gateway – 10.128.0.1 (which is the IP address of the router port that you are
connected to).
If you are using PC 2, 4, 6 or 8 configure the following:
2. IP address of PC - 10.128.1.2, subnet mask – 255.255.255.0, and default
gateway – 10.128.1.1 (which is the IP address of the router port that you are
connected to).
The configuration of the TCP/IP settings described above (these are the IP
address, subnet mask and default gateway), is illustrated below:
(N.B: Ignore the fact that the IP address is 202.0.0.2, it should actually be
10.128.0.2, and the gateway should be 10.128.0.1, instead of 202.0.0.1).
We will give an example of the 10.128.0.2 IP address for PCs 1, 3, 5 and 7. A
similar method can be used for PCs 2, 4, 6 and 8.

5. 5
Steps: ( “start”-“control panel”)/ at the right bottom on your computer you will find
the icon of- “network connections”-select “properties” of “local area connections”-
“general”-“internet protocol (TCP/IP)-“using the following IP address”
(Question: Why should we configure the default gateway as “10.128.0.1”?)

6. 6
(4) We use “telnet” to configure the routers (“start”→ “run”):
The telnet password for this lab is “huawei”. The IP address of the router port has
already been configured so you do not need to worry about it.

7. 7
(5) Abbreviation list (command can be abbreviated when typing if it does not
conflict with another command):
Normal Command Abbreviated

(6) When you finish the configuration, you can check the configuration by:
[RTA] display current-configuration
You can check the configuration of ports by:
[RTA] display interface
There are many more commands you can use which are not listed in this
manual.
(7) Type the first two/three letters of a command, the rest will be automatically
completed by pressing “Tab” button on the keyboard.
If you need help, then just type “?”, you may get the information you need.

3.1 Introduction to Huawei routers
3.1.1 Objective
Users will learn how to use Huawei routers, how to configure the IP address of
router ports, the IP address of the computer, and how to implement a network.
Users will also realize communication between two routers and two PCs.
3.1.2 Introduction
This lab will introduce you to the configuration of Huawei routers. In this
experiment, two routers are connected by a serial cable. Each router connects to
a PC.
This lab will use the default protocol configurations. We only configure the IP
address of the serial ports of Huawei routers and the IP address of PCs.
To enable the 2 PCs to communicate with each other:
1. Enter the configuration mode of each router’s serial port and set the IP
address.
2. Set the IP address of PCs 1, 3, 5 or 7, to 10.128.0.2 for the PCs 2, 4, 6 or 8 to
10.128.1.2.
3. You will telnet into the router IP address which will be 10.128.0.1 for PCs 1, 3,
5 or 7, and 10.128.1.1 for PCs 2, 4, 6 or 8, and use the login password “huawei”.
3.1.3 Preparation
Two PCs with 10/100M NIC installed
Two Routers (Quidway AR 28-31) with 100/1000M Ethernet ports, Serial
ports.
Console cable, Cross cables.

3.1.5 Experiment
1. Log in to the Router using:
• “telnet 10.128.0.1” for connections to routers 1, 3, 5 or 7. The login
password is “huawei”.
• “telnet 10.128.1.1” for connections to routers 2, 4, 6 or 8. The login
password is “huawei”.

2. Log in to the system and change the name of the router to RTA (if you are
accessing router 1, 3, 5 or 7). If you are accessing routers 2, 4, 6 or 8, change
the router name to RTB.
If you get informational (logging) messages on your console screen, such as the
ones shown below, ignore them and press “enter”, and continue with the lab.

11. 11
3. Enter the serial port S 1/1 of RTA, interface configuration mode
4. Set the IP address of S 1/1 of RTA: 192.0.0.1 255.255.255.0 and if you are
accessing RTB, set the IP address of its serial interface, S 1/1 to 192.0.0.2
255.255.255.0.
If you get the following log messages:
“Shutdown”
and “Undo
Shutdown” are
to refresh the
states of the
ports.

12. 12
Type “shutdown” then “enter”, followed by “undo shutdown” then “enter”.
5. The IP addresses of the E 0/0 ethernet ports were set before you began the
lab. This was done to enable you to access the router using the telnet program.
However for your own knowledge, the configuration of the IP address of an
Ethernet port (in this case E 0/0) is shown below:
Enter Ethernet port E 0/0 of RTA, interface configuration mode
Set the IP address of Ethernet port E 0/0 of RTA as: 202.0.0.1 255.255.255.0.
(N.B: In this case the IP address was set to 202.0.0.1, while in the actual lab
experiment, router RTA, was set to 10.128.0.1. The subnet mask is
255.255.255.0 in both cases).

13. 13
(Question: can we set the IP address here as 192.0.0.5 255.255.255.0? Why?)
The same steps can be carried out to configure the IP address of router RTB, to
10.128.1.1, and the subnet mask to 255.255.255.0.
6. Log in to RTB using the same step as RTA.
7. Set the IP address of S 1/1 of RTB to 192.0.0.2 255.255.255.0
8. Check the communication between the computers and the routers.
Using: “start”-“run”-“cmd”-“ on PCs 1, 3, 5 or 7:
ping 10.128.0.1
ping 192.0.0.1

14. 14
ping 192.0.0.2
From PCs 2, 4, 6 or 8:
ping 10.128.1.1, 192.0.0.2 and 192.0.0.1.
(Question: Why do we ping the IP addresses in this order from both PCs?)
3.1.6 Conclusion
When you check the configuration of RTA and RTB by:
[RTA]display interfaces
You will find that PPP encapsulation has automatically been selected for the
serial interfaces. That means the default protocol of the serial interface on a
Huawei router is PPP.
From this experiment we learn how to set the IP address of serial ports and
Ethernet ports, how to set the IP address of PCs, and how to check the
communication between the PCs.

15. 15
The steps are summarized:
(1) Log in to the routers.
(2) Set the IP address of serial port and Ethernet port of RTA and RTB.
(2) Set the IP address of the PCs.
(3) Check the result of this experiment whether PCA and PCB can communicate.

3.2.2 Introduction
PAP is a 2-handshake authentication and the password is transmitted in plain
text.
In the first lab of this chapter, we know that if we do not configure any protocol,
PPP will be automatically encapsulated.
This lab wants to configure PAP protocol to realize the communication between
two Huawei routers. Serial ports s 1/1 are selected to configure PAP protocol.

3.3 FRP (Frame Relay Protocol)
3.3.1 Objective
Learn to configure FRP.
Realize the communication of two routers with FRP protocol.
3.3.2 Introduction
The frame relay protocol is a kind of fast packet switching technology based on
X.25 protocol. FRP only implements the function of the core of the link layer;
therefore it is simpler and more efficient to forward or switch data units in the
data link layer.
This experiment has the following steps:
1. Encapsulate interface.
2. Configure the terminal type of frame relay interface.
3. Allocate DLCI on DCE.

3.5 X.25
3.5.1 Objective
Learn to configure X.25 protocol.
Realize the communication of two computer use X.25 protocol.
3.5.2 Introduction
The X.25 recommendation is the interface specification between the DTE and the
DCE. Its main function is to describe how to set up virtual circuit, transmission
packets, set up links, transmit data, release links and to clear the virtual circuits
between the DTE and the DCE, and in the meantime, it will implement the error
control, flow control, statistics, etc. And also it provides users with some optional
services and configuration functions. (Note: The DTE and DCE here are different
form the DTE and DCE of the physical interface. Here DTE means the user
equipment such as routers, etc; DCE means equipments such as packet switch,
etc. Route can also sever as the DCE.)
In the first experiment of this chapter, we know that if we do not configure any
protocol, PPP will be automatically encapsulated. That means this experiment
should configure X.25 by hand.
It has the following steps.
1. Set the IP address of the selected interface of the Router
2. Configure the interface to encapsulate it as the X. 25.
3. Specify its work model: DTE or DCE.
4. Specify the address mapping.
5. Set the flow control parameter.

3.6 FRS (Frame Relay Sub-interface)
3.6.1 Objective
Learn to configure FRS protocol.
Realize the communication among the computers with FRS
3.6.2 Introduction
FRS aims at solving the issue of split horizon in FR, therefore it adds a function
called sutinterface. That means on each physical interface we can set several
subinterfaces, each has its own IP address. The function of the subinterface is
the same as the physical interface, therefore the problem of split horizon is
solved.
This experiment has the following steps:
1. Configure the frame relay switch, enable frame relay switching, configure
frame relay interface type, and configure PVC route.
2. Create subterface, allocate DLCI, create address mapping, and configure IP
address on one Router.
3. Allocate DLCI, create address mapping, and configure IP address on other two
Routers.
3.6.3 Preparation
One PC with 10/100M NIC installed
Three Routers (Quidway AR 28-31) with 100/1000M Ethernet ports, Serial ports.
Console cable, Cross cables.

3.6.6 Conclusion
In FRS lab, we should follow three steps:
(1) Configure the frame relay switch (R4), including;
Set IP address, enable frame relay switching, configure frame relay
interface type, and configure PVC route.
(Question: Why should not we set the IP address here?)
(2) Configure R1, including:
Create subinterface, set up address mapping, allocate DLCI
(3) Configure R2 and R3, including:
Sep IP address, enable frame relay switching, create address mapping,
allocate DLCI.
