Hey guys. Just started working on my CCNA and i'm having a bit of trouble with routing this network.
I jumped into the course late so I missed subnetting and have been trying to work through it on my own. Think I got most of it down though.
It's no big deal if I don't get it down since we weren't supposed to really do anything till monday in class but I didn't feel like waiting around to try and follow along. Better if I can do it, get used to it, then go alone during class where I can expand upon my understanding.
We're using the CCNA network Visualizer 6 for this. (Really cool program btw lol)

Anyway on to the problem.
-Purple underlined IP's are concrete.
-I need to assign the missing IP addresses (yellow) with valid IPs, and all the hosts with valid IP's.
I think I got the hosts done properly, and they can all communicate on their own subnetworks.
Focusing on PEI on the right:
The problem starts when Hosts H01-H05 on PEI01 try to ping PEI Router Interface F0/0 (18.233.141.69) or any other hosts on the network. Nothing gets passed PEI01 switch interface F0/1 (pink arrow).
The in program troubleshooter says the interface is down, while the console says its up. Does the switch interface need an IP address? I didn't think it did but I tried adding one through the switches console just to see but it just returned an error.
I have the PEI router interface F0/0 set up as H01-H05's default gateway.
As far as communicated between router -> routers, and hosts -> hosts on other subnets:
I had PEI S0/1 @ 17.13.14.14/30
XFH01 S0/0 @ 13.100.200.158/30
FTN S0/1 @ 20.200.103.189/30
I assumed (perhaps incorrectly) PEI S0/1 should be on the same subnet as HFX01 S0/1 (same with other routers) but it didn't seem to work. Routers could ping their neighbours, but not hop one and ping the others. i.e. PEI couldnt ping FTN.
I set up RIP as the routing protocol and gave it the addresses on the neighbouring interfaces but it didn't seem to work.
Just in case, i tried giving the missing router IP interfaces completely separate IP addresses but that didn't seem to make a difference either.
Questions:
1)Was my assumption about the neighbouting router interfaces being on the same subnet correct? i.e. 17.13.14.13/30 ---------- 17.13.14.14/30 ? If not could someone give an example of a valid IP address for the PEI S0/1 router interface?
2)Did I subnet the hosts properly? I did the math for calculating block size and made sure I didnt use the subdomain address or broadcast address. Beyond that I don't know ^^;;
3) Pink arrow switch interface F0/1. Does it need an IP address? Would that be the default gateway instead of the router PEI F0/0? Or was choosing the router interface as the default gateway correct?
Thanks for any help anyone can offer. im stumped.
