Configuration Prerequisites
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.
Configuration Procedure
Follow these steps to configure an IPv6 over IPv6 tunnel:
To do… Use the command… Remarks
Enter system view 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
ipv6 address auto link-local
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.
