The tunnel-protocol command configures the tunnel protocol on a tunnel interface.

The undo tunnel-protocol command restores the tunnel protocol to the default configuration.

By default, no tunnel protocol is used on a tunnel interface.


CE6810LI does not support this command.


tunnel-protocol { gre | ipv6-ipv4 [ 6to4 ] | none }

undo tunnel-protocol


CE6870EI does not support 6to4 tunnel.


Parameter Description Value

Indicates that the GRE tunnel protocol is configured on a tunnel interface.


Configures the tunnel protocol of the tunnel interface as ipv6-ipv4 and uses a manual IPv6 over IPv4 tunnel.

ipv6-ipv4 6to4

Indicates that the IPv6 to IPv4 tunnel protocol is configured on a tunnel interface using 6to4.


Indicates that no tunnel protocol is configured on a tunnel interface.

Usage Guidelines

Usage Scenario

After creating a tunnel interface using the interface tunnel command, run the tunnel-protocol command to configure the tunnel encapsulation mode for the tunnel interface.

The following tunnel encapsulation modes are available:
  • GRE: encapsulates packets of some network layer protocols such as IP or IPX to enable these encapsulated packets to be transmitted on networks running other protocols such as IP.
  • IPv6-IPv4: creates tunnels on the IPv4 networks to connect IPv6 isolated sites so that IPv6 packets can be transmitted on IPv4 networks.


  • The none mode indicates the initial configuration, that is, no tunnel encapsulation mode is configured. In practice, you must select another tunnel encapsulation mode.
  • You must configure the tunnel encapsulation mode before setting the source IP address or other parameters for a tunnel interface. Changing the encapsulation mode of a tunnel interface deletes other parameters of the tunnel interface.
  • In IPv6 over IPv4 manual tunnel mode and 6to4 tunnel mode, the VPN scenario is not supported.


# Set the tunnel encapsulation mode of Tunnel2 to ipv6-ipv4.
