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

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-f1/0	connect to lan2
R2-f0/0	connect to lan3
R2-f1/0	connect to lan4
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)
