So this is due in tomorrow, and I have to idea why it wont work.
I was wondering if somebody could fix it, or at least tell me what was wrong with it.
I'm working on PC 21 - PC 17 packet sending.
It will send from router to router but never passed the switches.
Help is greatly appreciated.

Hello Patrick,
I am not going to solve your homework assignment for you, but a couple of observations that give you a hint what to correct:
Sorry for deliberately withholding the direct solution but I believe I am not wrong if I believe that you have the desire to be a knowledgeable networker. The ability to recognize and correct errors in a network topology is immensely important and I do not want to rob away from you the opportunity to improve that ability.
Please, feel welcome to discuss your partial solutions here!
Best regards,
Peter

He's not your pupil is he?

Leo,
No, he isn't But it would be REALLY funny if I stumbled across a post of my student trying to find out a solution to a homework I've assigned

Thanks I will give that a go and see what happens.
We have just been kind of thrown in the deep end. Its only one module of my degree, but it really isn't my strong point.
EDIT:
I have just changed the SW Routing table to include its own LAN and it has been a huge improvment allready! Thanks so much for your advice!

I changed the route table
I'm not working on the s0/0/1 part yet
The addressing was done on a VLSM table using the IPs that I was allocated. I really can not see anything wrong with them. While doing it I got no overlapping errors.
I tried to change the default gateway but it just says I can not use the other IPs, it is supposed to be the same IP as the interface connecting the switch with the router though right? That is what I did.
I have looked at everything suggested and it works a bit better now, it will get past the ISP router and onto the SW router (from WW) but it can not get past the SW LAN but then when the packets are going back it wont go past the SW router.

Patrick,

You do not have a network overlap between directly connected interfaces - a single router would tell you that. However, notice that
Does this not look like address overlap? Probably the mask on SW Fa0/1 was supposed to be /26 instead of /16.
I tried to change the default gateway but it just says I can not use the other IPs, it is supposed to be the same IP as the interface connecting the switch with the router though right?
By saying that the PCs are using strange gateways I wanted to say that both on PC21 and PC17, the default gateway is set to the broadcast address of the network. This cannot be - the default gateway is always the IP address of the router in the particular network. It cannot be a non-existent or unusable (network/broadcast) address.
Changing the routing tables should be probably done using an appropriate routing protocol in this network. You seem to have partially configured OSPF and RIPv2. None of them is completely configured, and you do not need two. I suggest not configuring things using static addressing - this assignment does not look like the correct solution is the static routing.
Best regards,
Peter
