OK I am a little new at this so bare with me. I should also say that cisco routing is really not my bag, this project was just thrown in my lap. I have a dedicated t1 line between my main office and data location. at the end of each t1 circuit is a cisco 1721 router. Each router has a WIC-1/DSL module installed.

on router a I have it set where the serial is 65.206.187.111 with the internal set at 10.2.0.2

at the datalocation i have the serial ip set at 63.111.2.33 and internal is 10.2.0.1.

My question is do I need to set something else? Like to tell each router to look at each other. If so how would I do this?

Thanks,
Jeff

Jeff,

First, you may have to change your internal network address at one or both of your locations.

Second, given your serial IP addresses, you don't have a dedicated T-1 between these two sites. Who gave you the IP addresses to use on your serial lines?

If you really have a dedicated T-1 between your two locations the following will work.

Lines beginning with an exclamation point are simply comments.

! I'm assuming the internal interface is fastethernet and your serial interface is Serial 0, it may also be serial 0/0. Change these if necessary.

Location 1:

interface serial 0
ip address 10.0.0.1 255.255.255.0

interface fastethernet 0
! this address with this mask will give you 253 addresses for users at this location
ip address 10.2.0.2 255.255.255.0

! The following will tell the router to learn about routes on your networks.
router eigrp 1
network 10.0.0.0

Location 2:
interface serial 0
ip address 10.0.0.2 255.255.255.0

interface fastethernet 0
ip address 10.1.0.2 255.255.255.0

router eigrp 1
network 10.0.0.0

Good luck
Bill
