z 

Configure IP addresses for interfaces (such as the VLAN interface, and loopback interface) on the 

device to ensure normal communication.  

z 

Specify one of the above interfaces as the source interface of the tunnel. 

z 

Ensure reachability between the tunnel source and destination addresses. 

Follow these steps to configure an IPv6 over IPv6 tunnel: 

Enter system view 

— 

Enable IPv6 

ipv6 

Required 

By default, the IPv6 packet 
forwarding function is disabled. 

Enter tunnel interface view 

Interface tunnel number 

— 

ipv6 address { ipv6-address 
prefix-length | 
ipv6-address/prefix-length } 

Configure an 
IPv6 global 
unicast 
address or  
site-local 
address 

ipv6 address 
ipv6-address/prefix-length 
eui-64 

Configure 
an IPv6 
address for 
the tunnel 
interface 

Configure an 
IPv6 link-local 
address 

ipv6 address ipv6-address 
link-local 

Required 

Use one of the commands. 

By default, no IPv6 address is 
configured for the tunnel interface.

Specify the IPv6 over IPv6 
tunnel mode 

tunnel-protocol ipv6-ipv6 

Optional 

By default, the tunnel is a GRE 
over IPv4 tunnel. The same tunnel 
mode should be configured at both 
ends of the tunnel. Otherwise, 
packet delivery will fail. 

Configure a source address 
or interface for the tunnel 
interface 

source { ipv6-address | 
interface-type 
interface-number } 

Required 

By default, no source address or 
interface is configured for the 
tunnel. 

Configure the destination 
address for the tunnel 
interface 

destination ipv6-address 

Required 

By default, no destination address 
is configured for the tunnel.
