OSPF - Route selection

Posted on 2013-09-26

Last Modified: 2013-09-26

I have two Cisco routers connecting between site A and site B and configured OSPF on the both routers.  There are one layer 3 switches at each location connected to those two routers.

Right now, it seems like it is doing loadbalancing between the routers.

For example, when I traceroute from siteA to site B, it goes trhough router A then when I traceroute again and it goes through routerB.  Back and forth, constantly.

How do I make it so that it only goes through routerA and when routerA fails, then go through router B without using the static route.

I'm trying to use router B as backup only.
