Viewing Two Global IPv6 Addresses
Important Points to Remember — virtual-ip
You can configure two global IPv6 addresses on the system in EXEC Privilege mode. To view the addresses,
use the show interface managementethernet command, as shown in the following example. If you try
to configure a third IPv6 address, an error message displays. If you enable auto-configuration, all IPv6
addresses on that management interface are auto-configured. The first IPv6 address that you configure on
the management interface is the primary address. If deleted, you must re-add it; the secondary address is not
promoted.
The following rules apply to having two IPv6 addresses on a management interface:
• IPv6 addresses on a single management interface cannot be in the same subnet.
• IPv6 secondary addresses on management interfaces:
• across a platform must be in the same subnet.
• must not match the virtual IP address and must not be in the same subnet as the virtual IP.

If there are two RPMs on the system, configure each Management interface with a different IP address. Unless
you configure the management route command, you can only access the Management interface from the
local LAN. To access the Management interface from another LAN, configure the management route
command to point to the Management interface.
Alternatively, you can use the virtual-ip command to manage a system with one or two RPMs. A virtual IP
is an IP address assigned to the system (not to any management interfaces) and is a CONFIGURATION mode
command. When a virtual IP address is assigned to the system, the active management interface of the RPM is
recognized by the virtual IP address — not by the actual interface IP address assigned to it. During an RPM
