Configuring an IPv6 manual tunnel

Configuration prerequisites

Configure an IP addresses for the interface (such as a VLAN interface, or loopback interface) to be
configured as the source interface of the tunnel interface.

Configuration guidelines

Follow these guidelines when you configure an IPv6 manual tunnel:
•
After a tunnel interface is deleted, all features configured on the tunnel interface are deleted.
•
Specify public addresses or interfaces as the source and destination addresses for the tunnel
interfaces.
•
If the destination IPv6 network is not in the same subnet as the IPv6 address of the tunnel
interface, you must configure a static route destined for the destination IPv6 network. You can
specify the local tunnel interface as the output interface of the route or specify the IPv6 address
of the peer tunnel interface as the next hop. Instead, you can enable a dynamic routing protocol
on both tunnel interfaces to achieve the same purpose. For the detailed configuration, see
Layer 3—IP Routing Configuration Guide.

Configuration procedure

To configure an IPv6 manual tunnel:
Step
1. Enter system view.
2. Enable IPv6.
3. Enter tunnel
interface view.
4. Configure an IPv6
address for the
tunnel interface.
5. Specify the IPv6
manual tunnel
mode.
Command
system-view
ipv6
interface tunnel number
•
Configure a global unicast IPv6
address or a site-local address:
ipv6 address { ipv6-address
prefix-length |
ipv6-address/prefix-length }
ipv6 address
ipv6-address/prefix-length
eui-64
•
Configure a link-local IPv6
address:
ipv6 address auto
link-local
ipv6 address ipv6-address
link-local
tunnel-protocol ipv6-ipv4
192
Remarks
N/A
By default, the IPv6 packet forwarding
function is disabled.
N/A
The link-local IPv6 address
configuration is optional.
By default:
•
No IPv6 global unicast address or
site-local address is configured for
the tunnel interface.
•
A link-local address is
automatically created when an
IPv6 global unicast address or
site-local address is configured.
By default, the tunnel mode is GRE over
IPv4.
The same tunnel mode should be
configured at both ends of the tunnel.
Otherwise, packet delivery fails.
