Configuring a tunnel interface 
Configure a Layer 3 virtual tunnel interface on each device on a tunnel so that devices at both ends can 
send, identify, and process packets from the tunnel.

Configuring a 6to4 tunnel 
Configuration prerequisites 
Configure IP addresses for interfaces (such as the VLAN interface, and loopback interface) on the device 
to ensure normal communication. One of the interfaces will be used as the source interface of the tunnel. 
Configuration guidelines 
Follow these guidelines when you configure a 6to4 tunnel: 
•   No destination address needs to be configured for a 6to4 tunnel because the destination address 
can automatically be obtained from the IPv4...

The same tunnel mode should be 
configured at both ends of the tunnel. 
Otherwise, packet delivery will fail. 
6.
