8.3.2.4. ipv6 address
Use this command to configure an IPv6 address on an interface, including tunnel and loopback interfaces, and to
enable IPv6 processing on this interface. You can assign multiple globally reachable addresses to an interface by
using this command. You do not need to assign a linklocal address by using this command since one is
automatically created. The <prefix> field consists of the bits of the address to be configured. The <prefix_length>
designates how many of the high-order contiguous bits of the address make up the prefix.
You can express IPv6 addresses in eight blocks. Also of note is that instead of a period, a colon now separates
each block. For simplification, leading zeros of each 16 bit block can be omitted. One sequence of 16 bit blocks
containing only zeros can be replaced with a double colon "::", but not more than one at a time (otherwise it is
no longer a unique representation).
Dropping zeros:
3ffe:ffff:100:f101:0:0:0:1 becomes 3ffe:ffff:100:f101::1
Local host
: 0000:0000:0000:0000:0000:0000:0000:0001 becomes ::1
Any host:
0000:0000:0000:0000:0000:0000:0000:0000 becomes ::
The hexadecimal letters in the IPv6 addresses are not case-sensitive. An example of an IPv6 prefix and prefix
length is 3ffe:1::1234/64.
The optional [eui-64] field designates that IPv6 processing on the interfaces was enabled using an EUI-64
interface ID in the low order 64 bits of the address. If you use this option, the value of <prefix_length> must be
64 bits.
To remove all IPv6 addresses or specified IPv6 address on an interface, use the no form of this command. If you
do not specify any parameter, the command deletes all the IPv6 addresses on an interface.
Format ipv6 address <prefix> / <prefix_length> [{eui64 | link-local}]
no ipv6 address [<prefix> / <prefix_length>] [{eui64 | link-local}]
Fields
Definition
<prefix>
The parameter consists of the bits of the address to be configured.
<prefix_length>
This option designates how many of the high-order contiguous bits of the
address comprise the prefix.
[eui-64]
This field designates that IPv6 processing on the interfaces was enabled using
an EUI-64 interface ID in the low order 64 bits of the address. If you do not
