Configuring a Backup Router (NSM Procedure)

During the time that the router is booting, the routing protocol process (RPD) is not running; therefore, the router has no static or default routes. When the routing protocol process fails to start properly, it stops the router from booting. To allow the router to boot and also to ensure that the router is reachable over the network, you configure a backup router. A backup router is a router that is directly connected to the local router (that is, on the same subnet).

To configure a backup router:

  1. In the NSM navigation tree, select Device Manager > Devices.
  2. Click the Device Tree tab, and then double-click the device for which you want to configure the backup router.
  3. Click the Configuration tab. In the configuration tree, select System > Backup Router.
  4. Enter a comment in the Backup Router workspace that describes the backup router.
  5. Enter an address in the Backup Router workspace for the backup router to use while booting.
  6. In the configuration tree, select System > Backup Router > Destination.
  7. Click + to enter a new destination address for the backup router.
  8. Click one:
    • OK—Saves the changes.
    • Cancel—Cancels the modifications.
    • Apply—Applies the backup router configuration settings.
