Syntax Description

tunnel_name Specifies an IPv6 tunnel.
source-address Specifies an IPv4 address for the tunnel.



Usage Guidelines

This command will create a new IPv6-to-IPv4 (also known as a 6to4 tunnel), and add it to the system. Only one 6to4 tunnel can be configured on any particular VR.

The tunnel name must be unique and cannot overlap the same name space as VLANs, other tunnels, or VRs. The name must begin with an alphabetical character and may contain alphanumeric characters and underscores ( _ ), but it cannot contain spaces. The maximum allowed lengthfor a name is 32 characters. For name creation guidelines and a list of reserved names, see Object Names.

The source address of the tunnel must be one of the IPv4 addresses already configured on the switch. You cannot remove an IPv4 address from the switch if a tunnel that uses it still exists.


The following example creates the 6to4 tunnel "link35" with source address

create tunnel link35 6to4 source
