# ipsec option dpd

#### Syntax

[ no ] ipsec option dpd

#### Release Information

Command introduced before JUNOSe Release 7.1.0.

#### Description

Enables IPSec dead peer detection (DPD) for the current virtual router. With DPD enabled, the router detects when connectivity between the router and an IPSec peer has been terminated. The router then sets the status for the tunnel and the upper layer interfaces to down, which enables routing protocols to take alternate routes. Also, administrators can then take corrective action. The no version restores the default DPD setting, disabled.

#### Mode

Global Configuration
