Configuring a 6to4 tunnel
Follow these guidelines when you configure a 6to4 tunnel:
•
You do not need to configure a destination address for a 6to4 tunnel, because the destination IPv4
address is embedded in the 6to4 IPv6 address.
•
The source addresses of local tunnels of the same tunnel mode cannot be the same.
•
Automatic tunnels do not support dynamic routing. You must configure a static route destined for the
destination IPv6 network if the destination IPv6 network is not in the same subnet as the IPv6
address of the tunnel interface. You can specify the local tunnel interface as the egress interface of
the route or specify the IPv6 address of the peer tunnel interface as the next hop of the route. For
more information about route configuration, see Layer 3—IP Routing Configuration Guide.
To configure a 6to4 tunnel:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter 6to4 tunnel interface
view.
interface tunnel number [ mode
ipv6-ipv4 6to4 ]
N/A
3.
Specify an IPv6 address
for the tunnel interface.
By default, no IPv6 address is
configured for the tunnel interface.
4.
Configure a source
address or source
interface for the tunnel
interface.
source { ip-address | interface-type
interface-number }
By default, no source address or
source interface is configured for the
tunnel interface.
The specified source address or the
primary IP address of the specified
source interface is used as the source
IP address of tunneled packets.
5.
(Optional.) Set the DF bit
for tunneled packets.
tunnel dfbit enable
By default, the DF bit is not set for
tunneled packets.
6.
Return to system view.

N/A
7.
(Optional.) Enable
dropping of IPv6 packets
using IPv4-compatible
IPv6 addresses.
tunnel discard
ipv4-compatible-packet
By default, this feature is disabled.
