ipv6 address
This command configures an IPv6 global unicast address and enables IPv6
on an interface. Use the no form without any arguments to remove all
IPv6 addresses from the interface, or use the no form with a specific IPv6
address to remove that address from the interface.
Syntax
ipv6 address [general-prefix-name] ipv6-address/prefix-length
no ipv6 address [[general-prefix-name] ipv6-address/prefix-length]]
• general-prefix-name - The label assigned to the general prefix which
specifies the leading bits of the network portion of the address.
• ipv6-address - A full IPv6 address if no general prefix is used, or the
subsequent bits following the general prefix if one is used followed
by the host address bits. The address must be formatted according
to RFC 2373 “IPv6 Addressing Architecture,” using 8
colon-separated 16-bit hexadecimal values. One double colon may
be used in the address to indicate the appropriate number of zeros
required to fill the undefined fields.
• prefix-length - A decimal value indicating how many contiguous bits
(from the left) of the address comprise the prefix (i.e., the network
portion of the address). The length of this prefix includes both the
general prefix and any number of subsequent IPv6 prefix bits
specified in this command. If the prefix length specified by this
command is shorter than the general prefix, then the length of the
general prefix takes precedence.
Default Setting
No IPv6 addresses are defined
Command Mode
Interface Configuration (VLAN)
Command Usage
• The general prefix normally applies to all interfaces, and is therefore
specified at the global configuration level. The subsequent network
prefix bits normally apply to one or more specific interfaces, and are
