ipv6 address link-local


ipv6 address link-local [<IPV6-ADDR>/<MASK>]


Enables IPv6 on the current interface. If no address is specified, an IPv6 link-local address is auto-generated for the interface. If an address is specified, auto-configuration is disabled and the specified address/mask is assigned to the interface.

To disable IPv6 link-local on the interface, remove ipv6 address link-local, ipv6 address <global-ipv6-address>, and ipv6 address autoconfig from the interface.


This feature is not available on the management VRF.

Command context




Specifies the IP address in IPv6 format (xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx), where x is a hexadecimal number from 0 to F. You can use two colons (::) to represent consecutive zeros (but only once), remove leading zeros, and collapse a hextet of four zeros to a single 0. For example, this address 2222:0000:3333:0000:0000:0000:4444:0055 becomes 2222:0:3333::4444:55.


Specifies the number of bits in the address mask in CIDR format (x), where x is a decimal number from 0 to 128.


Operators or Administrators or local user group members with execution rights for this command. Operators can execute this command from the operator context (>) only.


Enabling IPv6 link-local on the interface:

switch(config)# interface 1/1/1
switch(config-if)# ipv6 address link-local
