    Hi guys im new to the forum so apolagies if ive posted this in the wrong section! Im doing a project for college in which ive been asked to design the following scenario:

    Design a set of four networks inter-connected via routers (one must be a class A network, one a class B network and two class C sub-networks. The sub-networks must be derived from one and the same class C network).

    • Assign IP addresses to all connecting routers and one host computer in each network.

    Ive drawn a rought sketch up and now reproduced a simple version in visio. Just needing any help of advice to make sure im getting the right idea.


    So far this is my understanding of the challenge...

    Class A network: Router IP: Mask: and connected host IP: with Mask:
    Class B network: Router IP: Mask: and connected host IP: with Mask:

    Class C Subnet1: Router IP: Mask: and connected host IP: with Mask

    Class C Subnet2: Router IP: Mask: and connected host IP: with Mask

    Its asking for 2 subnets from a class C network so ive worked it the two above IP's from that creating as many host's as possible.

    I hope this makes sense! If its unclear please tell me and ill try my best to explain. Thanks for any input!

    Just a bit of an update... not sure if this makes more sense?

    Just a quick question mate.
    How do you have connected the sub networks and Are they connected to the same router via 2 fast Ethernet ports?
    One thing about the links between routers, I'd create a sub network of just 2 possible hosts within the range of the sub network ( for security purposes.
    Another thing is even though you were asked to create 4 networks don't forget that the links between routers are also considered a single network so lets say that if you have the asked 4 networks between 4 routers in reality you'd end up with 8 networks altogether mate.
    Hope I didn't confused you. Anything please ask us.
    Take care.

    Yeah ive sorted myself out now...thanks for the relpy anyway!

    I used PacketTracer to put in all the IP's and Subnets and now realise I had the total wrong end of the stick.

    This is an image of what i created although its got no details of IP's and such...


    All i need to do now is change the mini-subnets ive got connecting the routers so there is only 2 host's possible...

    This is what i have drawn up in visio now.


    Thanks for the reply though :)
