Configuring an ISATAP tunnel

Follow these guidelines when you configure an ISATAP tunnel:
•
You do not need to configure a destination address for an ISATAP tunnel, because the
destination IPv4 address is embedded in the ISATAP address.
•
Do not specify the same source addresses for local tunnel interfaces in the same tunnel mode.
•
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 more information about route configuration, see Layer 3—IP Routing
Configuration Guide.
To configure an ISATAP tunnel:
Step
1. Enter system view.
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
IPv6 packets that use
IPv4-compatible IPv6
addresses.

Remarks
N/A
N/A
By default, no IPv6 address is
configured for the tunnel
interface.
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.
By default, the DF bit is not set
for tunneled packets.
N/A
By default, IPv6 packets that use
IPv4-compatible IPv6 packets
are not dropped.
