This depends on how flexible the PBR implementation on your router is. If your router can have conditionals like this: * match: source address A && link P available --> send it to link P * match: source address A --> unconditionally send it to fallback link F
It doesn't necessarily have to be that complex OR brittle. I would suggest the use of recursive next-hop with PBR to the loopback /32 of a peer router that is not associated with a directly connected network. If that /32 route happens to be down, then the recursive lookup of the next-hop results in a lookup of the default route. -- -JH
