Configuring An Ipv6 Over Ipv4 Manual Tunnel - HP 6125XLG Layer 3-Ip Services Configuration Manual

Step
5. Set the MTU of the tunnel
interface.
6. Set the expected bandwidth for
the tunnel interface.
7. Set the ToS for tunneled packets.
8. Set the TTL for tunneled packets.
9. (Optional.) Restore the default
settings of the tunnel interface.
10. (Optional.) Shut down the tunnel
interface.

Configuring an IPv6 over IPv4 manual tunnel

Follow these guidelines when you configure an IPv6 over IPv4 manual tunnel:
The tunnel destination address specified on the local device must be identical with the tunnel source
•
address specified on the tunnel peer device.
Do not specify the same tunnel source and destination addresses for the tunnels in the same mode
•
on a device.
• If the destination IPv6 network is not in the same subnet as the IPv6 address of the tunnel interface,
you must configure a static route destined for the destination IPv6 network. You can specify the local
tunnel interface as the egress interface or specify the IPv6 address of the peer tunnel interface as the
next hop. Alternatively, you can enable a dynamic routing protocol on both tunnel interfaces to
achieve the same purpose. For detailed configuration, see Layer 3—IP Routing Configuration
Guide.
To configure an IPv6 over IPv4 manual tunnel:
Step
1. Enter system view.
2. Enter IPv6 over IPv4 manual
tunnel interface view.
Command

Command

Remarks
The default MTU is 64000 bytes.
Set an appropriate MTU to avoid
fragmentation. The MTU for the
tunnel interface applies only to
unicast packets.
An MTU set on any tunnel interface is
effective on all existing tunnel
interfaces.
By default, the expected bandwidth is
64 kbps.
The expected bandwidth for the
tunnel interface affects the link cost
value. For more information, see
Layer 3—IP Routing Configuration
Guide.
The default setting is the same as the
ToS of the original packet.
The default TTL for tunneled packets is
255.
N/A
By default, the tunnel interface is
enabled.
