Statement introduced before Junos OS Release 7.4.
Set a default router (running IP version 4 [IPv4]) to use while the local router (running IPv4) is booting and if the routing protocol processes fail to start. The Junos OS removes the route to this router as soon as the software starts.
Default: All hosts (default route) are reachable through the backup router.
