Syntax
ipv6 address
ipv6-prefix / prefix-length eui-64
no ipv6 address [ ipv6-prefix / prefix-length eui-64]
Parameters
• ipv6-prefix —Specifies the global unicast IPv6 address assigned to the
interface. This argument must be in the form documented in RFC4293
where the address is specified in hexadecimal using 16-bit values between
colons.
• prefix-length —The length of the IPv6 prefix. A decimal value that indicates
how many of the high-order contiguous bits of the address comprise the
prefix (the network portion of the address). A slash mark must precede the
decimal value.
Default Configuration
No IP address is defined for the interface.
Command Mode
Interface Configuration mode
User Guidelines
If the value specified for the
prefix-length argument is greater than 64 bits, the
prefix bits have precedence over the interface ID.
The IPv6 address is built from
ipv6-prefix and the EUI-64 Interface ID by the
following way:
• The first prefix-length bits are taken from ipv6-prefix .
• If prefix-length < 64 then
- The following (64-
prefix-length ) bits are filled by 0s.
- The last 64 bits are taken from the EUI-64 Interface ID.
• If prefix-length equals to 64 then the following 64 bits are taken from the
EUI-64 Interface ID.
• If prefix-length > 64 then the following (128- prefix-length ) bits are taken from
the last (64-(
prefix-length -64)) bits of the EUI-64 Interface ID.
