IPV6 COMMANDS
IPV
6 ENABLE
ipv6 enable
Overview Use this command to enable IPv6 on an interface without an IPv6 global address
for the interface. This enables IPv6 with a IPv6 link-local address, not an IPv6 global
address.
Use the no variant of this command to disable IPv6 on an interface without a global
address. Note the no variant of this command does not operate on an interface
with an IPv6 global address or an interface configured for IPv6 stateless address
autoconfiguration (SLAAC).
Syntax
ipv6 enable
no ipv6 enable
Mode Interface Configuration for a VLAN interface.
Usage 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 link-local addresses are retained in the system until they are negated by
using the no variant of the command that established them.
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 IPv6 with only a link-local IPv6 address on the VLAN interface vlan2,
use the following commands:
awplus# configure terminal
awplus(config)# interface vlan2
awplus(config-if)# ipv6 enable
To disable IPv6 with only a link-local IPv6 address on the VLAN interface vlan2,
use the following commands:
awplus# configure terminal
awplus(config)# interface vlan2
awplus(config-if)# no ipv6 enable
