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.
