Command Remarks
4. Configure an IPv6 address
for the tunnel interface.
• Configure an IPv6 global unicast
address or site-local address:
{ ipv6 address { ipv6-address
prefix-length |
ipv6-address/prefix-length }
{ ipv6 address
ipv6-address/prefix-length
eui-64
• Configure an IPv6 link-local
address:
{ ipv6 address auto link-local
{ ipv6 address ipv6 address
link-local
The IPv6 link-local address
configuration is optional.
By default:
• No IPv6 global unicast
address is configured for the
tunnel interface.
• A link-local address is
automatically generated
when an IPv6 global unicast
address or link-local address
is configured.
5. Specify the ISATAP tunnel
mode.
tunnel-protocol ipv6-ipv4 isatap
The default mode is GRE. The
same tunnel mode should be
configured at both ends of the
tunnel. Otherwise, packet
delivery fails.
6. Configure a source
address or interface for the
tunnel.
source { ip-address | interface-type
interface-number }
By default, no source address or
interface is configured for the
tunnel.
7. Return to system view.

8. Enable dropping of IPv6
packets using
IPv4-compatible IPv6
addresses.
tunnel discard ipv4-compatible-packet
Optional.
Disabled by default.
Configuration example
Network requirements
As shown in Figure 103, configure an ISATAP tunnel between the router and the ISATAP host so the
ISATAP host in the IPv4 network can access the IPv6 network.

Configuration procedure
Make sure GigabitEthernet 2/0/1 on the ISATAP router and the ISATAP host can reach each other
through IPv4.
• Configure the router:
