Configuration Example - H3C MSR 2600 Configuration Manual

Because automatic tunnels do not support dynamic routing, configure a static route destined for the
•
destination IPv6 network at each tunnel end. 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 source addresses of local tunnels of the same tunnel mode cannot be the same.
To configure an ISATAP tunnel:
Step
Enter system view.
1.
2. Enter ISATAP 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
The default setting is disabled.
