<br>
As far as I know the router will drop traffic for prefixes that are not in the FIB rather than attempt to route packets in software. However, to keep everything predictable I'd recommend supplementing your BGP table with a default route to more capable routers and/or filter out more specific prefixes you don't need so as to reclaim FIB space. <br>
<br>
Best regards, <br>
