When enabling ISATAP on a tunnel interface, an explicit IPv4 address is
configured as the tunnel source, or an automatic mode exists, where the
lowest IPv4 address is assigned to an IP interface. This source IPv4 address is
used for setting the tunnel interface identifier according to ISATAP
addressing conventions. When a tunnel interface is enabled for ISATAP, the
tunnel source must be set for the interface in order for the interface to
become active.
An ISATAP address is represented using the [64-bit prefix]:0:5EFE:w.x.y.z,
where 5EFE is the ISATAP identifier and w.x.y.z is a public or private IPv4
address. Thus, a Link Local address will be represented as FE80::5EFE:w.x.y.z
After the last IPv4 address is removed from the interface, the ISATAP IP
interface state becomes inactive and is represented as Down, however the
Admin state remains Enabled.
When defining tunneling, note the following:
• An IPv6 Link Local address is assigned to the ISATAP interface. The initial
IP address is assigned to the interface, and the interface state becomes
Active
.
• If an ISATAP interface is active, the ISATAP router IPv4 address is resolved
via DNS by using ISATAP-to-IPv4 mapping. If the ISATAP DNS record is
not resolved, the ISATAP host name-to-address mapping is searched in the
host name cache.
• When an ISATAP router IPv4 address is not resolved via the DNS process,
the status of the ISATAP IP interface remains Active. The system does not
have a default gateway for ISATAP traffic until the DNS procedure is
resolved.
• In order for an ISATAP Tunnel to work properly over an IPv4 network, an
ISATAP router must be set up..
