Anyldustries is large company with business in Engineering, Telecommunication and banking. The west end site has the users of Administration, HRU and the Executive group. Client looks forward to 100% growth in network over the next five years. We have developed this document as per company requirements for proposed network.
Summarized requirements for this network are given below:
West End Site has 88 users in the Admin group, 54 users in the HRU group, and 24 users in the Executive group. Each users group must be on separate subnet.
100 and 500 users for the East and South East networks
9 wireless hosts and 3 VLAN divided on separate subnets.
In order to maximise the IP address, VLSM shall be used.
Implementation of IP address and VLSM:
VLSM has been implemented in order to save IP address space as per client requirements. In addition VLSM has designed such a way so that it could support network growth of 100% over next five years.

Implementation of Routing:
Muddy Creek Company has decided OSPF as their preferred protocol for the network. This decision is backed by several reasons. Both version of RIP have slow convergence speed and only support 15 hosts. Due to potential future expansion plan of Muddy Creek RIP cannot be used here. As EIGRP is Cisco proprietary protocol, it is unable to support any device but Cisco. Moreover, it has medium scalability. Muddy Creek network also has the requirement of having designated router. With high convergence speed, no upper limit of hop count OSPF is requires little network overhead. It nicely supports routers from different manufactures in a large and complex network. As such it justifies the choice of preferred protocol for network.

Implementation of VLANs, VTP and switch network
Anyldustries has main office in Muddy Creek with very large geographical area. West End Site of this company has Administration, HRU and Executive group. All groups located in all three buildings. West End Site ICT staff in the main building also has Wireless router. In order to logically group them we used VLANs as employees from all users group place over all three buildings. In our Network design we also bear in mind 100% potential future growth over next five years as per client requirements. By using STP we can have redundant links which would support future expansion and backup in time of network failure. Moreover, as all users group placed over all three buildings, multiple VLANs been used. Since all VLANs are dividing in a separate broadcast domain, each one must have its own root bridge.
Rapid STP roots bridges design and implementation
Verification strategies and results
We have used various techniques in order to make proper network functionality. Appropriate 'show' commands should be used to examine the configuration of router and switch. Administrator should verify the configuration and rectify the any inaccuracy if found. 'debug' commands can be used to verify the processes and communications happening either within or between devices. 'debug' output messages need to verify carefully to determine proper functionality of the devices. In order to test the connectivity of the devices a sample host can be used.
Recommendations for future network upgrade
As per client requirement we have considered 100% potential growth of the company in the next five years. Company can upgrades to more up-to-date technologies as the network capacity grow, and faster, lower priced routers and switches become more available. Moreover, enough redundancy and VLAN facilitate the growth and easy expansion of the potential future network capacity. Additional cabling capacity also been considered to have room for future growth. Cat 5e used which would support enough speed (100 Mbps) as per current requirements. Client can replace cabling with newest optical fibre to support much higher bandwidth (40 Gbps) in near future.
