Configuring IPv6 addressing

In the default configuration on a VLAN, any one of the following commands enables IPv6 and creates a link-local address. Thus, while any one of these methods is configured on a VLAN, IPv6 remains enabled and a link-local address is present.

ipv6 enable
(See Enabling IPv6 with an automatically configured link-local address.)
ipv6 address autoconfig
(See Enabling autoconfiguration of a global unicast address and a default router identity on a VLAN.)
ipv6 address dhcp full [rapid-commit]
(See Enabling DHCPv6.)
ipv6 address fe80:0:0:0: <interface-identifier> link-local
(See Statically configuring a link-local unicast address.)
ipv6 address <prefix:interface-identifier>
(See Statically configuring a global unicast address.)

NOTE:

Addresses created by any of these methods remain tentative until verified as unique by Duplicate Address Detection (DAD). See Duplicate Address Detection (DAD).
