# interface tunnel

#### Syntax

[ no ] interface tunnel interfaceSpecifier [ transport-virtual-router vrName ] [ ipsec-transport ]

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Creates a tunnel interface for use by DVMRP, GRE, IPSec, or MPLS. You can specify that the tunnel be established in the routing space of a virtual router other than the current VR. If you specify another VR, all tunnel commands apply to the tunnel in that VR. If you do not specify another VR, tunnel commands apply to the current VR. For DVMRP and GRE tunnels, you can specify that the tunnel be protected with IPSec in transport mode. The no version removes the tunnel interface.

#### Options

- interfaceSpecifier—Particular interface; format varies according to interface type; see Interface Types and Specifiers
- vrName—Name of virtual router (other than the current VR) in which the tunnel will be established
- ipsec-transport—Indicates that the tunnel is protected with IPSec in transport mode; used for GRE or DVMRP tunnels only
