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

Wan link122.22.3.176/30255.255.255.252

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-f0/0connect to lan1
R1-f1/0connect to lan2
R2-f0/0connect to lan3
R2-f1/0connect to lan4
R1-loopback1loopback1
R2-loopback2loopback2
R1-s2/0connect to r2
R2-s2/0connect 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:

NameTypeAddress
bkacad.comA Record122.22.3.67
ftp.test.comA Record122.22.3.68
www.cisco.comA Record122.22.0.2
www.test.com A Record122.22.3.66

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):
    • pc1/cisco
    • pc4/cisco

Configuring the Mail client:

PCEmail addressIncoming and Outgoing mail serveruserpass
PC1pc1@bkacad.combkacad.compc1cisco
PC4pc4@bkacad.combkacad.compc4cisco

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
