Mostly the answer to your questions depends on how you have configured PBR.
In the most simple case where you have just configured PBR and set the next hop, if the router knows that the next hop is not available then it does not do PBR and will just use the default routing. This probably works ok if the next hop is over a point to point serial interface. Otherwise you probably need to get involved with PBR verify-reachabilty (which gets you into IP SLA etc).
If the router does recognize that the PBR next hop is not reachable (which may require tracking and IP SPA) then the traffic will just use the normal routing table logic.
- Whether BGP is up or is down does not change how PBR attempts to forward traffic. I am not sure what part of my response you interpret to say that BGP plays any role in PBR.
Based on the very limited information that you have provided I would think that your router WAN IP would be the appropriate next hop. Beyond that I would need to have more information about your environment and how your PBR is configured.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
