Cisco 2600/3640 WIC-2T

jwood1650

Level 1

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

inte s0

clock rate 2000000

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"

HTH

It show the protocol as down, how do I enable it?

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?

HTH

I am using two DTE cables to connect the two...

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?

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?

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

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)

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

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.

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
