To take care of inbound traffic over s0/1 also, you'll need to shutdown the s0/1 interface (no shut) or have your provider remove their routing over that circuit as well.

Question
Cisco 2600 Router
I have a Cisco 2600 router at the head end of my internet service. I have two T1-SCU/DSU installed in it, and two T1 circuits providing internet connectivity.
The two circuts (Serial0/0 and Serial 0/1) have unique IP addresses and I have the following enabled on both cards:
ip load-sharing per-packet
I have two default routes setup, one points to Serial0/0 the other to Serial 0/1
We are having major problems with the Telco on the Serial0/1 circuit and EVERYTHING is very slow.
While they fix this, how can I temporarly disable ANY traffic going out over Serial 0/1?
1.5MB/sec is better than what we are currently getting as the other interface is taking errors.
Here is the complete running configuration:

Answers
I have removed the route, and shutdown the interface as suggested.
With the interface shutdown, hoever will the Telco still be able to loop the CSU on the router while they are performing intrusive testing?
One other off-topic question, do I need to have the command
ip load-sharing-per packet
on both the Serial0/0 interface and the Serial 0/1 for it to work properly?
>With the interface shutdown, hoever will the Telco still be able to loop the CSU on the router while they are performing intrusive testing?
Yes.
One other off-topic question, do I need to have the command
ip load-sharing-per packet
This provides more equal usage of both circuits but can lead to out of order delivery so it is recommended to not do per packet load balancing. You can remove the command from the interfaces to do per-destination load balancing.
