8.2. Loopback Interface Commands
The commands in this section describe how to create, delete, and manage loopback interfaces. A loopback

receive both local and remote packets. The loopback interface is typically used by routing protocols. To assign an
IP address to the loopback interface, please refer to “ip address” command. To assign an IPv6 address to the
loopback interface, please refer to “ipv6 address” command.
