Chapter 10 Configuring Network Access
Configuring Virtual Context BVI Interfaces
Peer IPv6 Address To configure an IPv6 peer global address, 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.
Note The IPv6 peer global address must be unique across multiple
contexts on a shared VLAN.
Prefix Length Enter the prefix length for all global addresses to specify how many of
the most significant bits (MSBs) are used for the network identifier.
Enter an integer from 3 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 Unique-Local Address A unique local address is an optional IPv6 unicast address that is used
for local communication within an organization and it is similar to a
private IPv4 address (for example, 10.10.2.1). Unique local addresses
have a global scope, but they are not routable on the internet, and they
are assigned by a central authority. All unique local addresses have a
predefined prefix of FC00::/7. You can configure only one IPv6 unique
local address on an interface.
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.
