Syntax

interface tunnelmode {gre ipv4 | ip 6in4 | ip 6in6} interface tunnelno interface tunnel

Description

Creates or updates an IP tunnel. After you enter the command, the firmware switches to the configuration context for the tunnel.

If the specified tunnel exists, this command switches to the context for the tunnel.

By default, all tunnels are automatically assigned to the default VRF when they are created.

Parameters

mode {gre ipv4 | ip 6in4 | ip 6in6}
Creates an IP tunnel. Choose one of the following options:

  • gre ipv4: Creates a GRE tunnel.

  • ip 6in4: Creates an IPv4 tunnel for IPv6 traffic.

  • ip 6in6: Creates an IPv6 tunnel for IPv6 traffic.

Specifies the number for a new tunnel. Range: 1 to 127. Numbering is shared between all tunnels, so the same tunnel number cannot be used for an IPv6 in IPv4 tunnel and a GRE tunnel.

Specifies the number for an existing IP tunnel. Range: 1 to 127.
