Steps in designing a computer network

1) Determine the physical network layout
2) List down the network address and default subnet mask
3) Determine the minimum subnets and hosts per subnet to be supported
4) If you are implementing subnetting, you need a new subnet mask.
5) Use 2^N and 2^H-2 to determine the subnet bits and hosts bits to use
4) Derive the new subnet mask.
5) List down the network addresses, range of usable host ip addresses and broadcast addresses
6) Assign the network addresses to each LAN segment
7) Assign and configure the host ip addresses to the host devices in each LAN segment

Please click on the link below and setup the network as shown in the diagram.

You are required to setup all routers with the hostname and passwords. All PCs should be able to ping one another.

Good luck.

Follow your skill level and go through the slides. If you feel comfortable, go through the higher level slides as well and finally, attempt the quiz.

After learning NWF and INTT, you become IP Man (叶问）

In this network,

http://dl.dropbox.com/u/55776142/Assymetric%20Routing.pkt

You configure static routes such that when you ping PC1 to PC2, the ICMP request packets travel from Router A, Router B and Router D. On the other hand, the ICMP reply packets travel from Router D, Router C and Router A. The forward and return paths are different. This is known as assymetric routing. Kungfu routing.

Try this during the next lesson.

When mistakes are made....

Mistakes are made so that you can learn from them. In the process, you gain better insights so that you will not repeat them when you move on to higher level of study or go out to work. Usually when mistakes are made, you tend to remember them longer than just mere memorization of facts. Hence, it is important that you keep an open mind towards learning, have no fear about making mistakes during the course of learning, learn to think beyond the content and ask why or why not things can be done in different ways. It is the quality of your thoughts that counts, not the quantity of details which you memorized and almost surely, forget one month after the exam.

Learning by questioning, learning by doing, learning by teaching others
