Step Command Remarks 4. Configure an IPv6 address for the tunnel interface. • 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 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. 5. Specify the IPv6 manual tunnel mode. tunnel-protocol ipv6-ipv4 6. Configure a source address or interface for source { ip-address | interface-type the tunnel. interface-number } 7. Configure a destination address for destination ip-address the tunnel. 8. Return to system view. quit 9. Enable dropping of IPv6 packets using IPv4-compatible IPv6 addresses. tunnel discard ipv4-compatible-packet IPv4 over IPv4 tunnel by default. The same tunnel mode should be configured at both ends of the tunnel. Otherwise, packet delivery will fail. By default, no source address or interface is configured for the tunnel. By default, no destination address is configured for the tunnel. N/A Optional. Disabled by default. Configuration example Network requirements As shown in Figure 64, two IPv6 networks are connected over an IPv4 network. Configure an IPv6 over IPv4 tunnel between Switch A and Switch B to make the two IPv6 networks reachable to each other. If the destination IPv4 address cannot be automatically obtained from the destination IPv6 addresses of packets, configure an IPv6 manual tunnel. Figure 64 Network diagram 127

Remarks
4.
Configure an IPv6
address for the tunnel
interface.
•
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
/

•
Configure a link-local IPv6 address:
{
ipv6 address auto link-local
{
ipv6 address
ipv6-address
link-local
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.
5.
Specify the IPv6
manual tunnel mode.
tunnel-protocol ipv6-ipv4
IPv4 over IPv4 tunnel by default.
The same tunnel mode should be
configured at both ends of the
tunnel. Otherwise, packet delivery
will fail.
6.
Configure a source
address or interface for
the tunnel.
source
{
ip-address
|
interface-type
interface-number
}
By default, no source address or
interface is configured for the tunnel.
7.
Configure a
destination address for
the tunnel.
destination
ip-address
By default, no destination address is
configured for the tunnel.
8.
Return to system view.

9.
Enable dropping of
IPv6 packets using
IPv4-compatible IPv6
addresses.

Optional.
Disabled by default.
Configuration example
Network requirements
As shown in
Figure 64
, two IPv6 networks are connected over an IPv4 network. Configure an IPv6 over
IPv4 tunnel between Switch A and Switch B to make the two IPv6 networks reachable to each other. If the
destination IPv4 address cannot be automatically obtained from the destination IPv6 addresses of
packets, configure an IPv6 manual tunnel.
