ipv6 enable


ipv6 enable

no ipv6 enable


This command enables IPv6 on the VLAN and automatically configures the VLAN's link-local unicast address with a 64-bit EUI-64 interface identifier generated from the VLAN MAC address if IPv6 has not already been enabled on a VLAN by another IPv6 command option.

If no other IPv6-enabling command is configured on the VLAN, the no form of the command disables IPv6 on the VLAN. See Commands to disable IPv6 on a VLAN.


Only one link-local IPv6 address is enabled on the VLAN interface. Subsequent static or DHCP configuration of another link-local address overwrites the existing link-local address.


With IPv6 enabled, the VLAN uses received RAs to designate the default IPv6 router.

After verification of uniqueness by DAD, a link-local IPv6 address assigned automatically is set to the preferred status, with a "permanent" lifetime.

Default: Disabled
