IPV6 COMMANDS
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 or a local loopback interface.
Usage notes Use this command to enable automatic configuration of IPv6 addresses using
stateless autoconfiguration on an interface, and enable IPv6.
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 the device keeps link-local addresses until you remove them with the no
variant of the command that established them. See the ipv6 enable command for
more information.
Also note that the device keeps the link-local address if the global address is
removed using a command other than the command that was 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 vlan2, use the commands:
awplus# configure terminal
awplus(config)# interface vlan2
awplus(config-if)# ipv6 address autoconfig
