differs from the one that the two SUBNETs share (in this case, 172.12.215.29 and
:ABCD.1235).
DUAL Mode, Ethernet Failover, Nonshared IP
Example 1-9 on page 1-19 shows how to configure a DUAL-mode SUBNET with
Ethernet failover, nonshared IP. This configuration is shown in Figure 5-4.
This example shows that:
•
When configuring a SUBNET for DUAL-mode Ethernet failover, set the FAMILY
attribute to DUAL.
•
For Ethernet failover with nonshared IP, you do not need to specify an
IPV6INTERFACEID attribute (and if you do, you must specify a different interface
ID on the associated SUBNET).
•
As you do not want the SUBNETs to share an IP address, each SUBNET can keep
the IPv6 addresses automatically assigned to it. You do, however, have the option
of specifying a prefix for the IPv6 addresses; the final addresses assigned to the
SUBNETs still differ in this case as the interface IDs are different (different
SUBNETs have different interface IDs). For an example of configuring Ethernet
failover with nonshared IP and specifying the prefix, see Example 8-5 on
Note. If you select the reserved IP address from a LIF on a different adapter, you can
replace the adapter without taking down TCP/IP communications.
