• Study carefully the following network diagram. You will be assigned TWO IP addresses to configure this network. 
You need to e-mail the lecturer to request the two IP addresses. 
The first IP address given will be used for the WAN links. 
The second IP will be used for the LANs. 

You need to reply with a confirmation e-mail once you have received your allocated IP address.

Use VLSM to configure the given network LAN and the WAN links. 
VLSM must be used in the MOST efficient way to subnet the LAN and the WAN links.
All the links between routers are WAN links.
Assessment is covered by 4 stages, each stage has various tasks to complete. 

Stage 1 of this assignment: 
Subnet the IP address 
State the subnet mask 
Choose an IP address for PC1(in LAN2), PC2(in LAN 6) and default gateway.
The LOWEST IP addresses of each subnet should be given to the two PCs. 
The HIGHEST IP addresses of each subnet are given as the default gateway.

Stage 2 of this assignment: 
Configure the four routers. 
Naming the routers as Router 1, Router 2, Router 3 and Router 4. 
Setting the secret password as ‘class’ on all routers. 
Configuring interfaces/PCs; 
Configuring TELNET on the Router 3 with a password of ‘xyz123’ and (a suitable) MOTD; 
Saving changes on the routers; 
Verifying basic configuration and router operations;

Stage 3 of this assignment: 
Ping from the PC1(in LAN2) to PC2(in LAN 6).

Stage 4 of this assignment (Routing Protocols configuration): 
Set up EIGRP (AS number = 20) on all routers. 
The clock-rate on the routers should be set to the values shown in the figure above.

The following is the submission requirement:

SECTION A:

eg 12345678.pkt 

SECTION B. 
1. On all the routers change the EIGRP Administrative Distance to 150. 
2. Backup the router configurations. 
3. Reboot all four routers. 
4. Copy and paste the router table for Router 3 below, and comment on any differences between this router table and 
the one above (14.) and explain why.
