Command Remarks
3. Enter tunnel interface
view.
interface tunnel number N/A
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
The default mode is GRE. The same
tunnel mode should be configured at
both ends of the tunnel. Otherwise,
packet delivery fails.
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
interface.
destination ip-address
By default, no destination address is
configured for the tunnel.
8. Return to system view.
quit N/A
9. Enable dropping of IPv6
packets using
IPv4-compatible IPv6
addresses.
tunnel discard
ipv4-compatible-packet
Optional.
This feature is disabled by default.
Configuration example
Network requirements
As shown in Figure 99, configure an IPv4 network between Router A and Router B so the two IPv6
networks can reach each other over the IPv4 network. The tunnel destination IPv4 address cannot be
automatically obtained from the destination IPv6 addresses of packets. Therefore, configure an IPv6
manual tunnel.
