# tunnel destination backup

#### Syntax

tunnel destination backup [ ipAddress | identity fqdn ]

no tunnel destination backup

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

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.

#### Options

- ipAddress—IP address of the interface on the destination router that serves as the backup IPSec tunnel endpoint
- fqdn—Fully qualified domain name of the interface on the destination router that serves as the backup IPSec tunnel endpoint; a maximum of 80 characters

#### Mode
