I have a question......I am trying to figure out a redundant link design. I have 3 locations A, B, and C. I have a T-1 link between A to B and A to C. We have ordered a backup link T-1 B to C. To further compound this I have a 4006 at site B and a 6509 at site A with a 10MB link going in between B and A. They want the fiber link to be primary for the A to B link and th T-1 to be backup. The A to C be primary with the B to C be the backup. The 6509 has layer 3 routing but the 4006 does not. I do have a drawing showing how this needs to go. I Know I can use the Backup command for the T-1's but can I also for the fiber link.
