Need Help Setting Up Failover & Redundancy

I'm pretty new at setting up Cisco Routers. I need your help here.

We have 2 T1s going to the same location. They are supposed to run concurrently, and be backups for each other. Right now I believe they are setup for load balancing, but I would also like them setup for Fail-over and Redundancy.

Can you help me with what commands I need to implement?

Here are my Show Run and Show Interfaces:

How best to set this up will depend upon the specifics of your environment and your requirements. Easiest is a simple MLPPP setup, most robust is redundant LANs feeeding redundant routers through physically diverse T1 to full redundancy at the other end. Inbetween are all shades of grey...

Availability -- Load Sharing -- Cost/complexity You only get to chose two out of three...

Good luck and have fun!
