Hi,
I am configuring up a P2P (T1 pipe) between two Cisco routers. I haven't done that before.
Attached are the configs.
I am just using a static route on each end pointing all traffic out of the serial interface.
The routers attach to the smartjack and not an external CSU/DSU.
The telco is just proving bandwidth between the 2 sites.
There is a 'site J' and a 'site B'
A PC will be hanging off of each end.
Question 1 - Do I need a CTRLR T1 0 card or a T1 DSU/CSU card in each router?
Question 2 - Is it ok to route, and not bridge across the T1?
Question 3 - Should the configs work?
Thanks!

Hello rfreytag
Question 1 - Do I need a CTRLR T1 0 card or a T1 DSU/CSU card in each router?
You need a T1 DSU/CSU card
Question 2 - Is it ok to route, and not bridge across the T1?
Yes, you should route. Use a /30 subnet to connect them together
Question 3 - Should the configs work?
You would need to assign /30 for the serial interface.(same subnet). In your config you have 2 different once.
Example for the serial interafce
10.1.1.2/30 for J router
10.1.1.1/30 for B router
If your serial interface is up, you should be able to ping from one site to the other.
Good Luck

They are on the same subnet if I am not mistaken
10.1.1.1 / 24
10.1.1.2 / 24
I set it up in a lab and it works fine. Thank you very much for your reply.

Rob,
Glad is working and yes you are correct. They are on the same subnet. I was probably looking at the wrong interface on one of the routers.
Just a note that you can, but you don't have to use /24 since this is a point-to-point network
