    Hi all hope you are all well and had a nice xmas.
    Im back again for a bit of help if thats OK

    I am currently studying CCNA through the cisco academy and i am at the end of first semester and i have to do a case study which i am struggling with a little and would appreciate any ideas for what i have to do.

    Basically i have to design a network for a company,it has to have 7 subnets which i can calculate no probs but where i confuse my self is with what hardware to use. I realise each subnet will need a router interface in order for the subnets to communicate with one another, but what is the best way to do this. do i just find a router with 7 or more ethernet ports and then have a switch for each subnet to connect to it?? or is there a better way. i am going to use cat 6 cabling running at 100 mbps and then for server room i will have gigabit ethernet in full duplex mode but although i understand the concept and theory of it obviously i havent designed a full network before and am unsure of what routers or switches to use

    hope ive made sense lol heads a bit mashed today

    any ideas would be appreciated

    thanks a lot

    What you need to use is called VLAN Trunking.

    Interesting scenario.

    I would look at the switching method using say cisco 2950 switches which run at 10/100 with trunking between the swtches if needed using 802.1q (the trunking method used on the 2950). You can create a seperate VLANs for each subnet therefore seperating their collision domains.

    Back Again lol

    Thanks everyone for there help so far

    ive decided to do 2 different networks(one vlan and one traditional Lan)

    Im just bit stuck in the best way to do the traditional lan

    if i have 7 subnets within one building and i need them to be able to communicate with one another what is the best way to do this without using a Vlan set up and only using routers and switches. Im just unsure, i know that i will need a router inteface for each subnet but what is the best way to do this?

    any ideas would be appreciated as im on the last stretch of the assignment and i am really happy with it so far and couldnt of got this far without help off everyone here

    thanks

    If I get you right your traditional network would be a legacy network were users connected to a hub, which may of been connected to some kind of bridge or router (if wide-area connectivity was required). Multiple hubs were interconnected to allow more users on the same segment. However with the cascading hubs there would be a bigger collision domain resulting in problems in your network hence the advent of VLANs which could seperate these large collisions domains.

    Cisco.com is always a good place to do research although finding stuff can be difficult. However try this link:

    Hope it helps.

    The only forseable way that I can think of to do that without using VLANS would be to have each subnet connected to a router configured with access lists?

    As I don't think that you can get a router with 7 ethernet ports on it you may have to use several routers linked through serial links.

    If you still intend to use routers then simon's comments are more than valid.

    You can add a number of modules to your router in order to attain your 7 ethernet ports e.g 2600, 4000 or the larger 7000 series (might be over doing a bit).

    Then you will need to configure your router and hosts (including their default routes) in order for traffic to flow between the different subnets.

    :D
