tunnel destination backup [ ipAddress | identity fqdn ]
no tunnel destination backup
Command introduced before JUNOSe Release 7.1.0.
Configures a backup tunnel destination for the remote IPsec tunnel endpoint. The backup tunnel is used when the IPSec tunnel destination is detected as unreachable by DPD. You can use either the IP address or fully qualified domain name (FQDN) to identify the backup tunnel; however, you must use the same type of identity that is used for the regular tunnel destination. The no version restores the default, in which the regular tunnel destination is also the backup tunnel destination.
