Configuring Virtual Context BVI Interfaces
Second VLAN
Enter the second VLAN whose bridge group is to be configured with
this BVI. This VLAN can be the server or client VLAN. Valid entries
are from 2 to 4094.
Second VLAN Description
Enter a brief description for the second VLAN.
Enable IPv6 Check the check box to enable IPv6 on this interface. By default, IPv6
is disabled. The interface cannot be in bridged mode. When you enable
IPv6, the ACE automatically does the following:
• Configures a link-local address (if not previously configured)
• Performs duplicate address detection (DAD) on both addresses
Clear the check box to indicate that IPv6 is disabled on this interface.
IPv6 Global Address A global address is an IPv6 unicast address that is used for general IPv6
communication. Each global address is unique across the entire Internet.
Therefore, its scope is global. The low order 64 bits can be assigned in
several ways, including autoconfiguration using the EUI-64 format. You
can configure only one globally unique IPv6 address on an interface.
When you configure a global address, the ACE automatically does the
following:
• Configures a link-local address (if not previously configured)
• Performs duplicate address detection (DAD) on both addresses
IPv6 Address To configure an IPv6 global address on an interface, enter a complete
IPv6 address with a prefix of 2000::/3 to 3fff::/3. For example, enter
2001:DB8:1::0.
Check the EUI-64 box to specify that the low order 64 bits are
automatically generated in the IEEE 64-bit Extended Unique Identifier
(EUI-64) format specified in RFC 2373. To use EUI-64, the Prefix
Length field must be less than or equal to 64 and the host segment must
be all zeros.
Alias IPv6 Address When you configure redundancy with active and standby ACEs, you can
configure a VLAN interface that has an alias global IPv6 address that is
shared between the active and standby ACEs. The alias IPv6 address
serves as a shared gateway for the two ACEs in a redundant
configuration. You can configure only one alias global IPv6 address on
an interface.
To configure an IPv6 alias global address, enter a complete IPv6 address
with a prefix of 2000::/3 to 3fff::/3. For example, enter 2001:DB8:1::0.
Note You must configure redundancy (fault tolerance) on the ACE for
the alias global IPv6 address to work.
