Not quite sure of the way to go about this
Essentially we have a OSPF+MPLS network, almost all of it is wireless
Some sites have 24/60/80ghz primary and 5ghz backup links. The 5ghz always sit idle until used, the main link has BFD for faster failover. But occasionally a link flaps in bad conditions
I want to send the VoIP traffic across the backup links at all times to minimize interruption if main link is unstable but still considered up

How should I be doing this?
I think I can't use static routes because then if the backup link fails, it won't move over to the primary link
I'm thinking the best way would be to run an extra OSPF instances on sites that have backup links, but I can't seem to get it to work. The instance just stays in the running=no state
Maybe a BGP instance?
Other?

Bump. Anyone?
