Red,
From what i have read here you can begin with a setup like this...
PART 1:
Run a serial cable from the 2610 to one of the 2503 routers making sure that the DCE end is plugged into the 2503.
Run the second serial cable from that 2503 to the second 2503 router but the DCE end of the cable should be plugged into the same 2503 router. It will look like this...
2610=DTE=serial=DCE=2503#1=DCE=serial=DTE=2503#2
Now you have to have one DCE and one DTE per cable.. This HAS to match the actual cable as it should be labelled DTE/DCE. So plug both DCE ends into the MIDDLE router (2503#1)
Once this is done you will log into 2503#1 and set the clock rate commands which is how you make the two interfaces on this router a DCE.
R2503>enable
R2503#conf t
R2503(config)int s0
R2503(config-if)clock rate 64000
R2503(config-if)no shutdown
R2503(config-if)<Press CTRL and Z>
R2503>enable
R2503#conf t
R2503(config)int s1
R2503(config-if)clock rate 64000
R2503(config-if)no shutdown
R2503(config-if)<Press CTRL and Z>
This is how you will set up the DTE/DCE aspects of this scenario. You will also have to configure IP addressing, routing protocols ETC.
This design will allow you to treat 2503#1 as a Frame Relay switch later when you reach that stage and will meet all CCNA design requirements.
PART 2:
You will want to connect the switches and there are several ways to do so... My suggestion would be to use the three crossover cables to uplink between the switches then use one of the regular straight through cables to run to the 2610 ethernet port. You can buy/make another crossover and run that between the 2503 transceivers to play later if you wish or change this configuration at any time.
The setup that I am discussing has one questionable area. You currently have a 10mbps ethernet port on the 2610 and that (should) not support Inter-VLAN Routing. (You will reach this later and it is an important CCNA concept). I have heard both sides of this argument.. ethernet does/does not support IVLR. My suggestion is to try it. I keep forgetting to.. LoL Try it and if it does not then you will waant to purchase an NM-1FE2W card (eBay). This will give you one Fast Ethernet Port that supports IVLR for sure as well as two additional WIC slots.
NOTE: You must have an IP Plus IOS in order to support IVLR. You can always check features at Cisco's Feature Navigator page:
Make sure to download the lab book that CiscoGuy mentioned from:
If that does not work then just go to lulu.com and search for CCNA until you find the free book (That is what I had to do)...
LASTLY,
"My apologies again especially to MACZEN if the questions are worded wrong"
No worries, please do not take offense if I request a better explanation. In this line of work a forums are an invaluable resource. Learning forum etiquette as well as developing the ability to make a positive and informative post that makes the question well defined is not an ability. It is a skill that you have to develop (I am still working on it... LoL) It is often overlooked so take time to practice while you can... It will save you a LOT OF HEADACHE later... Good Luck and please post any more questions. It takes me a while to respond right now because I am working on my Security and not in the forum as often as I would like to be!!!
