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 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 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.
For configuration details, see
"
Configuring basic IPv6 settings ."
By default, no IPv6 address is
configured for the tunnel
interface.
