interface tunnel

Use interface tunnel to create a tunnel interface, specify the tunnel mode, and enter tunnel interface view.

Use undo interface tunnel to delete a tunnel interface.

Syntax

interface tunnel number [ mode { gre [ ipv6 ] | ipv4-ipv4 | ipv6 | ipv6-ipv4 [ 6to4 | isatap ] | mpls-te } ]

undo interface tunnel number

Default

No tunnel interface is created on the device.

Views

Predefined user roles

network-admin

Parameters

number: Specifies the number of the tunnel interface, in the range of 0 to 1023.

mode gre: Specifies GRE/IPv4 tunnel mode.

mode gre ipv6: Specifies GRE/IPv6 tunnel mode.

mode ipv4-ipv4: Specifies IPv4 over IPv4 tunnel mode.

mode ipv6: Specifies IPv6 tunnel mode. Set this mode for IPv4 over IPv6 manual and IPv6 over IPv6 tunnels.

mode ipv6-ipv4: Specifies IPv6 over IPv4 manual tunnel mode.

mode ipv6-ipv4 6to4: Specifies 6to4 tunnel mode.

mode ipv6-ipv4 isatap: Specifies ISATAP tunnel mode.

mode mpls-te: Specifies MPLS TE tunnel mode.

Usage guidelines

To create a new tunnel interface, you must specify the tunnel mode in this command. To enter the view of an existing tunnel interface, you do not need to specify the tunnel mode.

A tunnel interface number is locally significant. The tunnel interfaces on the two ends of a tunnel can use the same or different interface numbers.

Examples

# Create a GRE/IPv4 tunnel interface Tunnel 1 and enter tunnel interface view.

<Sysname> system-view
[Sysname] interface tunnel 1 mode gre
[Sysname-Tunnel1]
