Look into Static route retain. Should keep the route in the forwarding table.
From Jniper site
<<< 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 again. To avoid this latency, routes can be flagged as retain, so that they are 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.

As far as the fallback 'default' route, if you are purchasing transit from someone, you could consider a last-resort default pointed at them. You can exclude routes like 10/8 etc by routing these to discard + install on your devices.
That only helps if the default gets installed first, though. If the default has to wait at boot in the krt-queue behind the 300k+ Internet-routes, I have not really gained anything... I suppose it is likely that a static default would be installed before the BGP sessions even come up. /Benny _______________________________________________ juniper-nsp mailing list juniper-nsp () puck nether net https://puck.nether.net/mailman/listinfo/juniper-nsp
