Networks

when you ping each interface and you've got to try to ping them, all what happens?

Why don't you run a running config for us and paste it [change passwords and IP values but be accurate when you change IP values e.g.

The 1721 is an Access Router, so do you have any access lists? If you have access lists defined, you might want to disable them and try a connection.

I can't see what type of encapsulation do you use on serial interfaces. I think you use Cisco T1/E1 Multiflex Voice/WAN Interface Cards.
In this case try to use this config.
Router datacenter:

controller T1 0
framing esf
clock source internal
linecode b8zs
channel-group 0 timeslots 1-24
!
interface Serial 0:0
ip address 10.1.0.1 255.255.255.0
encapsulation ppp
!
interface FastEthernet0/0
ip address 10.2.0.1 255.255.255.0
!
no router eigrp 1
!
ip route 10.0.0.0 255.255.255.0 serial 0:0

Router main office:

controller T1 0
framing esf
clock source internal
linecode b8zs
channel-group 0 timeslots 1-24
!
interface Serial 0:0
ip address 10.1.0.2 255.255.255.0
encapsulation ppp
!
interface FastEthernet0/0
ip address 10.0.0.2 255.255.255.0
!
no router eigrp 1
!
ip route 10.2.0.0 255.255.255.0 serial 0:0

hey guys here is the running config file:

I was told by another to actuallyget rid of eigrp and use a static route. with EIGRP on I was able to see each router on each side.

with the static route I can still see each router and can ping, but still cannot actually computer to computer from each network.

Seems like computers don't have routes to another network... What default router have computers in datacenter network? If not 10.2.0.1, then on each computer you need to add route:
route add -p 10.0.0.0 mask 255.255.255.0 10.2.0.1
And on each computer in main office:
route add -p 10.2.0.0 mask 255.255.255.0 10.0.0.1
(This commands for MS Windows)

I think I got it? if this is right then I think your going to laugh about it.

In the router with the serial address of 10.1.0.1 it has a static route of

10.2.0.0/24 goto 10.1.0.2

ip classless
ip route 10.2.0.0 255.255.255.0 10.1.0.2 permanent
no ip http server

and then on the router with the serial address of 10.1.0.2 you have a static that says?

10.0.0.0/24 go to 10.1.0.1

ip classless
ip route 10.0.0.0 255.255.255.0 10.1.0.1 permanent
no ip http server

You have them backwards I think. The router 10.1.0.1 also has the FE interface 10.2.0.1 on it? but your telling it that in order to get to that network you have to go to 10.1.0.2, which is the other router. Since there is no default route it drops the packets there.

Then the router 10.1.0.2 with FE 10.0.0.2 has a static route that sends 10.0.0.0 to 10.1.0.1. That router has no default gateway and drops those packets.

You just have to change the static routes around. You don?t even have to run EIGRP. Just make sure you can ping across from 1 router to the other first.

I e-mailed you my response. Good Luck!!

i wish for more info about exactly what server and application exactly needs to talk to each other. but having said that...just 2 cents:
tell mgmt you need replacement routers as cheap insurance for these single points of failure. say you need 2. call up cisco sales and tell them what you want to do. pump them for information. buy the spares pretend you are configuring them in advance as spares. this will get you a whole test lab thing going which is what you need. visit the cisco website and learn how to remotely configure and secure them, back them up and restore them. learn what breaks communication. figure out how you gonna reload your backup from afar when you accidently break tcpip. ask cisco to walk you thru setting up static routes. but tell them what you are trying to get done. maybe you need some port forwarding too. or something. do you require to browse the remote network. ask them for pointers on securing the routers

Well here it is with all that information that is on ee and your added suggestions, I am still only able to ping from router to router, but when I do a tracetr from each machine the packets are actually trrying to go out the public ports. Meaning I have on the main office a router that shooots out to the internet and a router that is supposed to go to the other LAN. On the datacnter side I have a line that goes to a bridge for our outside IP's, and a router for the main office location. For some reason everytime I try to ping all routes try to go out the public routers. Do you know what I have to do to get it to point to the private T1 router, and still have the outside addresses be public?
