7. Bind the tunnel to a VLAN with the tunnel source vlan command.
8. Assign an IPv6 global unicast address to the tunnel using the ipv6
address command.
9. Then check your configuration settings using the show ipv6 tunnel
command, and the interface status of the tunnel using the show ip
interface or show ip interface brief command.
interface tunnel This command configures an IPv6 to IPv4 tunnel interface and enters
tunnel configuration mode. Use the no form with a tunnel number to
remove a tunnel, or without a tunnel number to remove all tunnels.

◆ Although this command is labeled with the name “tunnel,” it allows
configuration of either a manually configured IPv6 over IPv4 transport
network based on RFC 2893, or of an automatic method of transporting
IPv6 traffic over IPv4 clouds without explicit tunnels using RFC 3056.
◆ Configured IPv6 over IPv4 tunneling uses point-to-point tunnels by
encapsulating IPv6 packets within IPv4 headers to carry them over
IPv4 routing infrastructures.
◆ Transporting IPv6 over IPv4 clouds (based on RFC 3056) defines a
method for assigning a unique IPv6 address prefix to any site that
currently has at least one globally unique IPv4 address, and specifies
an encapsulation mechanism for transmitting IPv6 packets using such a
prefix over the global IPv4 network.
