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: 10.0.0.0 Mask: 255.0.0.0.0 and connected host IP: 10.52.60.2 with Mask: 255.0.0.0
Class B network: Router IP: 168.17.0.0 Mask: 255.255.0.0 and connected host IP: 168.17.20.2 with Mask: 255.255.0.0

Class C Subnet1: Router IP: 192.168.1.0 Mask: 255.255.255.128 and connected host IP: 192.168.1.1 with Mask 255.255.255.128

Class C Subnet2: Router IP: 192.168.1.128 Mask: 255.255.255.128 and connected host IP: 192.168.1.129 with Mask 255.255.255.128

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?

Hello.
Just a quick question mate.
How do you have connected the sub networks 192.168.1.0 and 192.168.1.128? 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 (255.255.255.252) 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
