IPV ENABLE

ipv6 enable

Overview Use this command to enable automatic configuration of a link-local IPv6 address
on an interface using Stateless Automatic Address Configuration (SLAAC). By
default, the EUI-64 method is used to generate the link-local address.
Use the no variant of this command to disable IPv6 on an interface without a global
address. Note, to stop EUI-64 from generating the automatic link-local address, use
the command no ipv6 eui64-linklocal.
ipv6 enable
Syntax
no ipv6 enable
Mode Interface Configuration for a VLAN interface or a local loopback interface.
Usage notes The ipv6 enable command automatically configures an IPv6 link-local address on
the interface and enables the interface for IPv6 processing.
A link-local address is an IP (Internet Protocol) address that is only used for
communications in the local network, or for a point-to-point connection. Routing
does not forward packets with link-local addresses. IPv6 requires that a link-local
address is assigned to each interface that has the IPv6 protocol enabled, and when
addresses are assigned to interfaces for routing IPv6 packets.
Note that the device keeps link-local addresses until you remove them with the no
variant of the command that established them.
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.
Default All interfaces default to IPv6-down with no address.
Examples To enable IPv6 with only a link-local IPv6 address on the VLAN interface vlan2, use
the following commands:
awplus#
awplus(config)#
awplus(config-if)#
To disable IPv6 with only a link-local IPv6 address on the VLAN interface vlan2, use
the following commands:
awplus#
awplus(config)#
awplus(config-if)#
