New to Cisco, a little help very much appreciated

[Njetscreamer]

O.k. so have a background in firewalls and I figured I ought to do a little more work in other areas get a better understanding of routing and switching.

I got a little 2600 and a 1600 just to use for labs at home and have tried with no success to get the 2 talking to each other.

The are connected using a db60dce to AUI type connection DTE.
The WIC-1T and ethernet0 interface on the 1600 are bot link up, protocol down.

So the question is how do I get them to a proto up stage or am I flogging a dead horse here.

Any help, insight or even rude remarks to the form of what an idiot I am much appreciated

What port on the 2600 are you connecting the dte.dce cable to? Also could you please post the configs of both routers.

You need to use a protocol that both routers will understand, such as IGRP or RIP. If you do not have both routers configured using the same protocol, then the protocol will remain down.

would not use any routing protocols in this scenario, just make sure you have the cables connected the right way dte to dce, leave the encap as hdlc but dont forget to declare a link speed in the config of the serial int, this can be practically anything you like up to 4MB, above this the 1600 will start to play up.

Njetscreamer,
Since you are connecting your serial interfaces back to back with DTE at one end and DCE at the other you will need to set the "clock rate" command on the DCE interface since it is acting as the "provider".

Routers are normally DTE devices and clocking on the serial interface is set at the other end in the providers cloud.

You will also need to make sure both ends are using same encapsulation such as HDLC or PPP, HDLC is default on most Cisco routers.

If you are using IP addresses on these interfaces make sure they are in the same range and that you have no duplicate IPs.

I hope this helps!
