N/A.
This command creates a new IPv6-in-IPv4 (otherwise known as a configured tunnel or a 6in4 tunnel) and add it to the system. A maximum of 255 tunnels (including one 6to4 tunnel) can be configured on the system.
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 length for a name is 32 characters. For name creation guidelines and a list of reserved names, see Object Names in the ExtremeXOS 30.7 User Guide .
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 is still exists that uses it.
The following example creates the 6in4 tunnel "link39" with destination address 10.10.10.10 and source address 192.168.10.15:
create tunnel link39 ipv6-in-ipv4 destination 10.10.10.10 source 192.168.10.15
