Network Diagram, IP address = 122.22.0.0/22

A given network as in the diagram above, you need to perform the following tasks:

Section 1: Using VLSM to create the IP address plan

LAN1: 310 host addresses LAN2: 200 host addresses LAN3: 60 host addresses LAN4: 40 host addresses Loopback1: 30 host addresses Loopback2: 10 host addresses Wan link: 2 host addresses

Network Address Mask Des Mask

LAN1 122.22.0.0 /23 255.255.254.0

LAN2 122.22.2.0 /24 255.255.255.0

LAN3 122.22.3.0 /26 255.255.255.192

LAN4 122.22.3.64 /26 255.255.255.192

Loopback1 122.22.3.128 /27 255.255.255.224

Loopback2 122.22.3.160 /28 255.255.255.240

Wan link 122.22.3.176 /30 255.255.255.252

Section 2: assign IP addresses, subnet masks and default gateways to the networking

devices.

In each network, assign ip address follow this order

Address for interfaces of networking device (router’s interface) +1

Note: Address for interfaces of networking device with WAN link: router1 +1; router2 +2

Address for servers WEB, DHCP: +2 Address for servers MAIL, DNS: +3 Address for servers FTP, TFTP: +4 Address for PC clients PC4: +4 PC5: +5 PC6: +6

Ex: In the subnetwork: 192.168.1.128/25 (there are WEB, MAIL, TFTP, PC6)

Router’s interface: 192.168.1.129 WEB server: 192.168.1.130 MAIL server: 192.168.1.131 TFTP server: 192.168.1.132 PC6 client: 192.168.1.134

Section 3: Using Packet Tracer to perform the tasks

Note: You need accuracy, distinguish capital letters and lowercase letters (for ex: bannermotd of

router 1: router1, not Router1)

Basic router/switch configurations:

Hostnames: Assign the Routers names R1, R2.

Passwords & Banner Message: (Routers only).

Console and VTY lines and password, password=’class’. Set the privileged mode password: enable password=’class’, enable secret password=’cisco’. Banner contains the name of device: router1, router2. (type ‘#router1#’)

Routers interfaces:

Assign IP addresses and subnet masks Use the clock rate 64000 Create descriptions, Interface description:

R1-f0/0 connect to lan1




R1-loopback1 loopback1

R2-loopback2 loopback2

R1-s2/0 connect to r2

R2-s2/0 connect to r1

Static default route:

R1: (config)# ip route 0.0.0.0 0.0.0.0 s2/0 R2: (config)# ip route 0.0.0.0 0.0.0.0 s2/0

Backup configuration: Backup Router1/Router2 configuration on TFTP Server (server file

name: R1-confg, R2-confg)

Configuring the Servers and PCs

Assign an IP address and Subnet mask, Default gateway

Active suitable services

Configuring the DNS server:

Name Type Address

bkacad.com A Record 122.22.3.67

ftp.test.com A Record 122.22.3.68

www.cisco.com A Record 122.22.0.2

www.test.com A Record 122.22.3.66

Configuring the DHCP server:

Default Gateway: 122.22.2.1 DNS Server: 122.22.0.3 Start IP Address: 122.22.2.10 Subnet Mask: 255.255.255.0 Maximum number of users: 20 TFTP Server: 122.22.0.4

Configuring the MAIL server

Domain name: bkacad.com Add users and passwords (user/pass):

o pc1/cisco o pc4/cisco

Configuring the Mail client:

PC Email address Incoming and Outgoing mail server user pass

PC1 [email protected] bkacad.com pc1 cisco

PC4 [email protected] bkacad.com pc4 cisco

Send mail from pc1 to pc4 and check the result

Configuring the PC client:

PC0, PC1, PC2, PC3: Assign IP address, subnet mask, default gateway and DNS server address by DHCP server

PC4, PC5, PC6: Manual assign IP address, subnet mask, default gateway and DNS

Connectivity tests:

Ping from pc2 to pc5 to test whether the network operates successfully. Ping from pc1 to ftp.test.com to check the connection to the ftp server. Ping from pc1 to TFTP server to check the connection to the TFTP server. Ping from pc1 to DNS to check whether the connection to the DNS server. Ping from pc1 to Web: www.cisco.com to check the connection to the Web server. Ping from pc1 to Web: www.test.com to check the connection to the Web server. Ping from pc1 to Mail: bkacad.com to check the connection to the Mail server.

Create a .pkt file: After finishing the configuration tasks, students have to save it to

your_name.pkt file (example:NguyenVanA.pkt) and copy to the suitable folder

Storage the file on the server
