Chapter 10 Configuring Network Access
Configuring Virtual Context VLAN Interfaces
IPv6 Address To configure a unique local address, enter a complete IPv6 address with
an FC00::/7 prefix in the first field. In the second field after the /, enter
the prefix length to specify how many of the most significant bits
(MSBs) are used for the network identifier.
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.
IPv6 Peer Address In a redundant configuration, you can configure an IPv6 peer unique
local address on the active that is synchronized to the standby ACE. You
can configure only one peer unique local IPv6 address on an interface.
To configure a peer unique local address, enter a complete IPv6 address
with an FC00::/7 prefix in the first field. In the second field after the /,
enter the prefix length to specify how many of the most significant bits
(MSBs) are used for the network identifier.
Note The IPv6 peer unique local address must be unique across
multiple contexts on a shared VLAN.
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.
Prefix Length Enter the prefix length for all unique-local addresses to specify how
many of the most significant bits (MSBs) are used for the network
identifier. Enter an integer from 7 to 127. If you use the optional EUI-64
check box for the global and peer addresses, the prefix must be less than
or equal to 64.
IPv6 Link-Local Address By default, when you enable IPv6 or configure a global IPv6 address on
an interface, the ACE automatically creates a link local address for it.
Every link local address must have a predefined prefix of FE80::/10.
You can configure only one IPv6 link local address on an interface. This
address always has the prefix of 64.
To manually configure the link local address, enter a complete IPv6
address with an FE80::/10 prefix in this field. For example, enter
FE80:DB8:1::1.
