So I don't clutter up the lab thread I have already started.

Am I correct in assuming that you can hook up 2 routers together via the serial interface? Also I am assuming that you would have to assign a different IP adress to this interface than the one on the ethernet interface?

I have got 2 2503 routers.

wizard,

Yes, you can hook up 2 routers together via the serial interfaces. Make sure you're using an appropriate cable to connect the two serial ports.

Yes, you would need to assign a different IP address to the serial interface that you would assign to the ethernet interface. That's because each interface, serial or ethernet, "belongs" to the sub/network that it is connected to. Let the router figure out how to route packets from one interface to the other.

I hope this helps.

 

Yes it does thanks

I'll have some more questions down the line, just got to wait for the second switch I've ordered

 

New question

I now have 2 routers set up with the following IP addresses:

192.168.1.1 - Ethernet0
192.168.1.2 - Serial0

192.168.2.1 - Ethernet0
192.168.2.2 - Serial0

So now how would I set up a route so 1.x can see 2.x and vice versa?

I also have the Serial0 interfaces hooked up together

 

wizard,

First, think of the router ports like a computer NIC. Imagine two computers connected by a cross-over cable. What must be the common factor of the IP addresses of both ends of the crossover cable?

 

Okay I'll tackle that answer later.

I have another problem I tried to issue the no shutdown command to Serial 0 on the 192.168.2.1 router, I am now getting the following error message:

Code:

192.168.2.0 overlaps with Ethernet0
Serial0: incorrect IP address assignment

 

wizard,

Actually, that's a confirmation of the reason for my question. By answering my question, you'll solve that problem too.

 

Just one a little more digging one of the routers has to be set to DCE.

 

wizard,

You are correct. How do you configure the serial interface to be the DCE?

 

Okay it would seem that I have really jumped in further than I should have done at the moment. Been doing some more digging, it would seem I need other bits, so I'm going to take a step back and start from the beginning and actually start reading some CCNA material instead of appearing to be stumbling around. Thanks for the help so far, more questions will follow soon.
