The WAP device supports the Intra-Site Automatic Tunnel Addressing Protocol
(ISATAP). ISATAP enables the WAP device to transmit IPv6 packets encapsulated
within IPv4 packets over the LAN. The protocol enables the WAP device to
communicate with remote IPv6-capable hosts even when the LAN that connects
them does not support IPv6.

communicate with remote IPv6-capable hosts even when the LAN that connects
them does not support IPv6.
The WAP device acts as an ISATAP client. An ISATAP-enabled host or router must
reside on the LAN. The IP address or host name of the router is configured on the
WAP device (by default, it is isatap). If configured as a host name, the WAP device
communicates with a DNS server to resolve the name into one or more ISATAP
router addresses. The WAP device then sends solicit messages to the routers.
When an ISATAP-enabled router replies with an advertisement message, the WAP
device and the router establish the tunnel. The tunnel interface is assigned a
link-local and a global IPv6 address, which serve as virtual IPv6 interfaces on the
IPv4 network.

ISATAP Query Interval—Specifies how often the WAP device should send
queries to the DNS server to attempt to resolve the ISATAP host name into
an IP address. The WAP device sends DNS queries only when the IP address
of an ISATAP router is unknown. The valid range is 120 to 3600 seconds. The
