backup-router
Syntax
Hierarchy Level
Release Information
Statement introduced before Junos OS Release 7.4.
Description
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.
Options
address—Address of the default router.
destination destination-address—(Optional) Destination address that is reachable through the backup router. Include this option to achieve network reachability while loading, configuring, and recovering the router, but without the risk of installing a default route in the forwarding table.
 | Note: The backup router Routing Engine does not support more than 16 destinations. If you configure more than 16 destinations on the backup Routing Engine, the Junos OS ignores any destination addresses after the sixteenth address and displays a commit-time warning message to this effect. |
- Default: All hosts (default route) are reachable through the backup router.
Required Privilege Level
system—To view this statement in the configuration.
system-control—To add this statement to the configuration.
