6To4 Tunnel Configuration Example - HP 6125XLG Configuration Manual

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 the detailed configuration, see Layer 3—IP Routing Configuration Guide.
• The automatic tunnel interfaces using the same encapsulation protocol cannot use the same source
IP address.
To configure a 6to4 tunnel:
Step
Enter system view.
1.
2. Enter 6to4 tunnel interface
view.
3. Specify an IPv6 address
for the tunnel interface.
4. Configure a source
address or source
interface for the tunnel
interface.
5. (Optional.) Set the DF bit
for tunneled packets.
6. Return to system view.
7. (Optional.) Enable
dropping of IPv6 packets
using IPv4-compatible
IPv6 addresses.

Remarks
N/A
N/A
No IPv6 address is configured for the
tunnel interface by default.
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.
The DF bit is not set for tunneled
packets by default.
N/A
Optional.
The default setting is disabled.
