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.
• Do not specify the same source addresses for local tunnel interfaces in the same tunnel mode.
• 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.
See "Configuring basic IPv6
settings."
By default, no IPv6 address is
configured for the tunnel interface.
4. Configure a source
address or source
interface for the tunnel
interface.
source
{ ipv4-address |
interface-type interface-number }
By default, no source address or
source interface is configured for
the tunnel interface.
If you specify a source address, it
is used as the source IP address
of tunneled packets.
If you specify a source interface,
the primary IP address of this
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.
quit
N/A
7. (Optional.) Enable
dropping IPv6 packets
that use IPv4-compatible
IPv6 addresses.
tunnel discard
ipv4-compatible-packet
By default, IPv6 packets that use
IPv4-compatible IPv6 packets are
not dropped.
