Configuration Procedure; Configuration Example - HP A7500 Series Configuration Manual

The automatic tunnel interfaces using the same encapsulation protocol cannot share the same
•
source IP address.

Configuration procedure

Follow these steps to configure an ISATAP tunnel:
To do...
Enter system view
Enable IPv6
Enter tunnel interface view
Configure
an IPv6
address for
the tunnel
interface
Specify the ISATAP tunnel
mode
Configure a source address
or interface for the tunnel
Return to system view
Enable dropping of IPv6
packets using
IPv4-compatible IPv6
addresses

Configuration example

Network requirements
As shown in
hosts reside in the IPv4 network.
Configure the IPv6 hosts to access the IPv6 network through the ISATAP tunnel.
Use the command...
system-view
ipv6
interface tunnel number
Configure an ipv6 address { ipv6-address
IPv6 global prefix-length |
unicast ipv6-address/prefix-length }
address or
ipv6 address
site-local
ipv6-address/prefix-length eui-64
address
ipv6 address auto link-local
Configure an
IPv6 link-local
ipv6 address ipv6-address link-local
address

Remarks
—
Required
By default, the IPv6 forwarding
function is disabled.
—
Required.
Use either command.
By default, no IPv6 global unicast
address is configured for the tunnel
interface.
Optional
By default, a link-local address will
automatically be generated when
an IPv6 global unicast address or
link-local address is configured.
Required
GRE over IPv4 tunnel by default.
The same tunnel mode should be
configured at both ends of the
tunnel. Otherwise, packet delivery
will fail.
Required
By default, no source address or
interface is configured for the tunnel.
