Fundamentals of IPv6
specify the IPV6RAENABLE attribute as ON as shown in the example (Note that the
asterisk (*) specifies all TCPMONs on the system):
->ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, DEVICENAME LAN02, &
FAMILY INET6, IPV6RAENABLE ON
The host automatically assigns the interface ID portion of the address, receives
router advertisement packets from the router, and assigns a prefix (Assuming that
a router that supports the neighbor discovery protocol is available on the network).
If you want to use IP aliasing to have multiple IP addresses associated with an
interface (LIF), you have several options. You always receive two automatically
generated IPv6 addresses: the loopback address and one address created by the
host from the router-advertised prefix. You can also configure the router to
advertise more prefixes and this causes more automatic addresses for each
interface.
To add more alias IP addresses to an IPv6 interface, you can do one or more of
these actions:

You can add an address by using the IPV6ADDRESS attribute:
->ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, &
DEVICENAME LAN02, FAMILY INET6, &
IPV6ADDRESS "AB:CD:CE:AB::2bff:fe12:3456", &
IPV6RAENABLE ON
In which case, you have three or more addresses for the interface: one
address for each advertised prefix (you can configure the router to advertise
one or more prefixes), the link-local address, and the address that you
specified.

Or you can add one or more addresses by using the IPV6PREFIX attribute.
->ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, &
DEVICENAME LAN02, FAMILY INET6, &
IPV6PREFIX "3FFE:1200:214:1::/64", IPV6RAENABLE ON
When you add a prefix, you have multiple addresses for the interface: the link-
local address, the address that has the prefix that you specified, and as many
addresses as prefixes advertised by the router.
The other attribute that affects the address is IPV6INTERFACEID. This attribute
overrides the default interface ID assigned by the host. This attribute does not
result in additional addresses.
->ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, FAMILY INET6, &
DEVICENAME LAN02, IPV6INTERFACEID "::ABCD:1234"
If you do not want to enable auto-configuration, either do not specify the
IPV6RAENABLE attribute or specify the IPV6RAENABLE attribute with the value
OFF.
In addition to the unicast address, when you add an IPv6-type SUBNET, the host
generates a link-local address automatically. As every IPv6-type SUBNET has a
