3.2.2 Configuring ISATAP
Tunnel
This section introduces how to configure an ISATAP device.
On an ISATAP tunnel interface, the configuration of an ISATAP IPv6 address and the
advertisement configuration of a prefix is same to that of a normal IPv6 interface.
However, the address configured for an ISATAP tunnel interface must be a revised
EUI-64 address. The reason is that the last 32 bits of the interface identifier in the IPv6
address are composed of the IPv4 address of the interface referenced by the tunnel
source address. Refer to the above chapters and sections for the information about
ISATAP address formats.
Caution
A device supports multiple ISATAP tunnels. However, the source of each
ISATAP tunnel must be different.
Otherwise, there is no way to know which ISATAP tunnel a received ISATAP
tunnel message belongs to.
