Load Balancing T1/SDSL HELP - 1841 Router

[rchaney99]

I have a 1841. The router is not load balancing our T1 and SDSL connection correctly.

S/0/0 is the T1.

Fast Ethernet 0/1 is the SDSL Connection – this is a 4MB connection.

Sometimes the T1 will be at 100% utilized when the SDSL connection is only 3% utilized. Also then the SDSL Connection is Down, the T1 will not work. However, when the T1 is down, the SDSL connection will work.

Below is my config. If anyone can help, it would be greatly appriciated.

need a little more info about topology, like where each interface goes and its purpose. The current descriptors are a little confusing.

 

[rchaney99]

Not sure what you mean... They are both internet connections. The T1 goes to one service provider and the SDSL goes to another (they are sister companies that share IP addresses tho).

 

[rchaney99]

If this helps...

The T1 s/0/0/0 connects to a T1 card, and the SDSL FE 0/1 connects to a DSL modem.

The problem could be in your OER configuration.Try troubleshooting in that area.
