Look into Static route retain. Should keep the route in the forwarding tabl=

Route Retention
By default, static routes are not retained in the forwarding table when the=
routing process shuts down. When the routing process starts up again, any =
routes configured as static routes must be added to the forwarding table ag=
ain. To avoid this latency, routes can be flagged as retain, so that they a=
re kept in the forwarding table even after the routing process shuts down. =
Retention ensures that the routes are always in the forwarding table, even =
immediately after a system reboot.

That only helps if the default gets installed first, though. If the default=

I suppose it is likely that a static default would be installed before the =
BGP sessions even come up.
