Can someone walk me through the steps on how to configure my serial modules on my 2600 and 3640? Each router has the WIC-2T with two cables connecting them. I tried to ping one router from the other, but no luck. Serial IP address I just made up, this is my home lab, so if I messed those up some how, please let me know...
Here is the running config for each rotuer:

Ok, encapsulation looks good. You need to clock the DCE side of the cable.
sh contr se0 will tell you which side is DTE and which side is DTE
On DCE site

if this does not work try
clock rate 64000

Is this interface in up and up mode?

Are the physical interfaces in up and up mode? Can you issue this command on both routers and post them here?
"sh ip int bri"

Can you make sure encapsulation is the same for both interfaces? They should be HDLC by default. "sh int se0" on both routers
Are you using a serial interface to connect them together? what type cable is that?

One last question... since there are two ports on the interface card, can I connect the two routers by the two WIC ports? Would that have any advantage?
02-06-2012 06:42 PM
Yes, you can. Put the other interface in a different subnet.
Would that have any advantage?
Not in this case. If you had lets say 2 T1 connecting to the same provider, you could bundle the 2 together to get more bandwidth for a total of 3Mb.

Is it working now?

Well I jumped the gun, I can ping from the 192.168.3.1 router (2610) to the 192.168.2.1 router (3640), but not form 192.168.2.1 to the 192.168.3.1....any idea?
02-06-2012 06:48 PM
On the 2610 you need a static route like this:
ip route 192.168.2.0 255.255.255.0 10.0.1.2
on the 3640 you need a static route like this:
ip route 192.168.3.0 255.255.255.0 10.0.1.1
02-06-2012 06:55 PM
on the 3640 I get this:
3640-Internet(config)#ip route 192.168.3.0 255.255.255.0 10.0.1.1
%Invalid next hop address (it's this router)
02-06-2012 07:02 PM
switch them arounf
On the 2610 you need a static route like this:
ip route 192.168.2.0 255.255.255.0 10.0.1.1
on the 3640 you need a static route like this:
ip route 192.168.3.0 255.255.255.0 10.0.1.2
Basically on the 2610 you want to point to the serial interface of the 3640
On the 3640 you want to point to the serial interface of the 2610
02-06-2012 07:10 PM
So do I need to configure each port on the WIC card? Right now, I only have se0/0 configured and not se0/1? I can ping just fine from the 2600 to the 3640...but no success from 3640 to 2600.
02-06-2012 07:17 PM
You only need one serial interface on each router.
but with the static route I provide you. you should be able to ping from both router
if this is for lab use and not production, can you delete all the extra static routes on both routers and test again?
You just need the one I provided you
no ip route 192.168.2.0 255.255.255.0 192.168.3.0
no ip route 192.168.2.0 255.255.255.0 10.0.1.0
no ip route 192.168.3.0 255.255.255.0 192.168.2.0
no ip route 192.168.3.0 255.255.255.0 10.0.1.0
