IPV
6 ADDRESS AUTOCONFIG
ipv6 address autoconfig
Overview Use this command to enable IPv6 stateless address autoconfiguration (SLAAC) for
an interface. This configures an IPv6 address on an interface derived from the MAC
address on the interface.
Use the no variant of this command to disable IPv6 SLAAC on an interface. Note
that if no global addresses are left after removing all IPv6 autoconfigured
addresses then IPv6 is disabled.
Syntax
ipv6 address autoconfig
no ipv6 address autoconfig
Mode Interface Configuration for a VLAN interface.
Usage This command enables automatic configuration of IPv6 addresses using stateless
autoconfiguration on an interface and enables IPv6, but does not enable IPv6
forwarding. See the ipv6 forwarding command for further description and
examples.
IPv6 hosts can configure themselves when connected to an IPv6 network using
ICMPv6 (Internet Control Message Protocol version 6) router discovery messages.
Configured routers respond with a Router Advertisement (RA) containing
configuration parameters for IPv6 hosts.
The SLAAC process derives the interface identifier of the IPv6 address from the
MAC address of the interface. When applying SLAAC to an interface, note that the
MAC address of the default VLAN is applied to the interface if the interface does not
have its own MAC address.
If SLAAC is not suitable then a network can use stateful configuration with DHCPv6
(Dynamic Host Configuration Protocol version 6) Relay, or hosts can be configured
statically. See ip dhcp-relay server-address for the DHCPv6 Relay server command
description and examples. See the IP Feature Overview and Configuration Guide
for more information about DNS Relay.
Note that link-local addresses are retained in the system until they are negated by
using the no variant of the command that established them. See the ipv6 enable
command for more information.
Also note that the link-local address is retained in the system if the global address
is removed using another command that was not used to establish the link-local
address. For example, if a link local address is established with the ipv6 enable
command then it will not be removed using a no ipv6 address command.
Examples To enable SLAAC on the VLAN interface vlan2, use the following commands:
awplus# configure terminal
awplus(config)# interface vlan2
awplus(config-if)# ipv6 address autoconfig
