Introduction
This basic network design has been created to the University of Greenwich and it will explain all the implements that the whole network contains and how will that help to the users in all ends. The basic network design included three Routers and it has been separated in to three places as follows. 1. Greenwich 2. Avery Hill 3. Medway This network design has been created more securely. Workstation 2 and File server 1 are in the management management network. network. Any device on the management management network can access any device on the entire network. The estimated value for the devises on the whole network as follows: Devise Description

The above above pingin pinging g massag massages es are confirm confirming ing that that they they are pingin pinging g withou withoutt any restrictions, and now I would like to prepare the Access Control List. In order to create access control list it is very important to select the correct wildcard bits. It has been used most of the time 0.0.0.0 so it will check each bits for security recent, at that will help to protect the network.

Access Control Lists
1 Telnet Telnet from Medway Medwa y to Greenwich Successful
From Medway which is the Router name junaidMD, then telnet to Greenwich and it was successful. And password is required to access.
2 Telnet Telnet from workstation 4 to Greenwich blocked
Now it has been blocked 192.168.0.11 is workstation 4

Conclusion
This This netw networ ork k has has been been desi design gned ed to acces accesss from from thre threee place placess from from Avery very Hill Hill,, Greenwich, and Medway. To access any one, they will require a password unless the administrator allowed to access to the users without the passwords. The Routers have been given names but it can be changed, and without passwords these Routers can not be operated remotely remotel y or Telnet Telnet in to it. The whole network has been protected by the Access control List, so any one from out side can not get in to use the computers or the server. Devises have been supplied here are very good quality and can be find out any faults very quickly, so that will reduce the amount of time ti me wasting by students or the staffs at the University. If the University expect a high volume of computer users in future, this design has been created to add many numbers of computers depend on the requirements of the University. A Variable Variable Length Length Subnet Subnet Mask (VLSM) is a means of allocating allocating IP addressing addressing resources to subnets according to their individual need rather than some general network-wide rule. Of the IP routing protocols supported by Cisco,OSPF, Dual IS-IS, BGP-4, and EIGRP support "classless" or VLSM routes. So this is supporting to this whole network and in future many computers can be added if that necessary.

Welcome and Call to Order – Sylvanus Jenkins
Sylvanus Jenkins welcomed all members present. After brief introductions, the meeting was called to order at 3:00 p.m. Approval of Minutes Minutes from the last meeting: None Review Agenda for February 15, 2008 – Group Members
DISCUSSION SESSION Sylvanus Jenkins led the discussion of the meeting. During the discussion team members exchange contact with other team members Sylvanus Jenkins exchange with Sandra) since Akram was not present for the meeting we could not acquired any contact from him. We then then review review the assign assignmen mentt to begin begin assign assigning ing tasks tasks to each each indivi individua dual. l. Team members begin looking at the assignment and the required tasks. Group MEETING Sandra and Sylvanus Jenkins were to create the draft of the physical topologies. The first task was to work out the IP scheme scheme that the three networks networks that will be used. We then discuss amongst ourselves the given class of our IP scheme and our given range. Both members where to work out the IP schemed by the next meeting schedule meeting. Several nominations were made as to who might be able to serve on the group for the diary. Sylvanus Jenkins suggested the he will create the Diary and then Gantt chart as well as write minute of the meeting. To be completed by the next meeting: •
•

DISCUSSION SESSION Sylvan Sylvanus us Jenki Jenkins ns led the discus discussio sion n of the meetin meeting. g. Team members members were asked asked to produce the complete result from task given. Akram was not present for the meeting and could not be contacted from us. We then review the tasks each individual were suppose suppose to carry out by this meeting. Although an IP scheme had been worked out by Sylvanus Jenkins and Sandra it still was a concern as we had completed our task but it was not worked out properly. They were then told to look in to the problem and try to solve it by the third meeting. Team members looked in to the assignment and the required tasks. Group MEETING Sandra and Sylvanus Jenkins were told to create the second draft of the logical topology and physical topologies. The second agenda had been address already the (IP scheme) three networks had been created. The team then discuss the whether or not the current version of packet tracer had something to do with the IP scheme not working properly. We then discuss amongst ourselves how we can address the current developed problem. Several nominations were made as to who might be able to serve on the group for the diary diary.. Since Since Sylvan Sylvanus us Jenkin Jenkinss had created created the diary diary and Gant chart chart they they were were then then updated to remind ourselves of the progress made.

It was apparent to each individual the network is working. They then began to discuss the write up of the technical documentation. Several people made suggestions as to how this should be done in accordance with the required specification. We then review the progress made and record it in the diary. However during the meeting team members was alerted to that the network had not be advertise on the network and that needed to be done. Group MEETING The first meeting review was the first one where action is needed to be taken to address one team member.
