Configuring an IPv4 over IPv4 Tunnel

Configuration Prerequisites

Configure IP addresses for interfaces (such as the VLAN interface, and loopback interface) on the
device to ensure normal communication.
Specify one of the above interfaces as the source interface of the tunnel.
Ensure reachability between the tunnel source and destination addresses.
