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.
•
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.
•
The source addresses of local tunnels of the same tunnel mode cannot be the same.
To configure an ISATAP tunnel:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter ISATAP tunnel interface view. interface tunnel number [ mode
ipv6-ipv4 isatap ]
N/A
3.
Specify an IPv6 address for the
tunnel interface.
By default, no IPv6 address is
configured for the tunnel
interface.
4.
Configure a source address or
source interface for the tunnel
interface.
source { ip-address |
interface-type interface-number }
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.
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 of
IPv6 packets using
IPv4-compatible IPv6 addresses.
tunnel discard
ipv4-compatible-packet
By default, this feature is
disabled.
