•ISATAP Robustness—Used to calculate the interval for the DNS or router
solicitation queries. The larger the number, the more frequent the queries.
NOTE The ISATAP tunnel is not operational if the underlying IPv4 interface is
not in operation.
STEP 3 Click Apply. The tunnel is saved to the Running Configuration file.
Defining IPv6 Addresses
To assign an IPv6 address to an IPv6 Interface:
STEP 1 In Layer 2 system mode, click Administration > Management Interface > IPv6
Addresses.
In Layer 3 system mode, click IP Configuration > IPv6 Management and
Interfaces > IPv6 Addresses.
STEP 2 To filter the table, select an interface name, and click Go. The interface appears in
the IPv6 Address Table.
Click Add.
STEP 3 Enter values for the fields.
•IPv6 Interface—Displays the interface on which the IPv6 address is to be
defined. If an * is displayed, this means that the IPv6 interface is not enabled
but has been configured.
•IPv6 Address Type—Select the type of the IPv6 address to add.
-Link Local—An IPv6 address that uniquely identifies hosts on a single
network link. A link local address has a prefix of FE80, is not routable, and
can be used for communication only on the local network. Only one link
local address is supported. If a link local address exists on the interface,
this entry replaces the address in the configuration.
-Global—An IPv6 address that is a global Unicast IPV6 type that is visible
and reachable from other networks.
•IPv6 Address—In Layer 2, the device supports one IPv6 interface. In
addition to the default link local and Multicast addresses, the device also
automatically adds global addresses to the interface based on the router
advertisements it receives. The device supports a maximum of 128
addresses at the interface. Each address must be a valid IPv6 address that
