9 IPV6 Commands
9.1 Tunnel Interface Commands
The commands in this section describe how to create, delete, and manage tunnel
interfaces.Several different types of tunnels provide functionality to facilitate the transition of
IPv4 networks to IPv6 networks. These tunnels are divided into two classes: configured and
automatic. The distinction is that configured tunnels are explicitly configured with a destination
or endpoint of the tunnel. Automatic tunnels, in contrast, infer the endpoint of the tunnel from
the destination address of packets routed into the tunnel. To assign an IP address to the tunnel
interface, please refer to “ip address” command. To assign an IPv6 address to the tunnel
interface, please refer to “ipv6 address” command.
