I am working a solution to provide redundancy to a network that is running OSPF via satellite (ethernet via DMVPN tunnel) connections in area 0. The terminals are geographicaly located to take advantage of a fiber connection that is in OSPF area 1. I would like to take advantage of setting up the fiber as the redundant link (I know, fiber is better than satellite ... but there is a need to keep the primary route on satellite). Can I just set them up with a /30 area 1 network at each location and set the ospf cost higher than the primary links? Do I have to use the area default-cost command? How about floating static routes?
I have this problem too.
