Here is a question that was twice on a CCNA exam:
PC1--------> R1 ---------> R2 ---------> SW---------->PC2
You can see the IP for PC2 and you can log only on R1 via PC1
The exam asks to connect PC1 with PC2
- Log on R1 and find the IP of R2 with: #sh cdp neigh details
note: it's important to use "details" otherwise you won't be able to see the IP for R2.
- Telnet to R2 and run a #sh cdp neigh details, but that will not help you get the IP of the switch. Apparently, the switch has not been assigned an IP.
I am not sure if you will be able to ipconfig /all on PC2.
Enable routing and adding the networks did not help. ...
It's a nice simulation to waste your time and stay behind with the rest of the questions.
