Enabling IPv6 on an Interface
You can enable IPv6 at the interface level.
The following example enables IPv6 for an Ethernet interface.
device# configure terminal device(config)# interface ethernet 1/1/1 device(config-if-e1000-1/1/1)# ipv6 enable
Note: In the preceding example, the interface is
assigned an automatically computed link-local address. When configuring VLANs
that
share a common tagged interface with a physical or Virtual Ethernet (VE) interface,
your should override the automatically computed link-local address with a manually
configured unique address for the interface. If the interface uses the automatically
computed address, which in the case of physical and VE interfaces is derived from
a
global MAC address, all physical and VE interfaces will have the same MAC address.
To override a link-local address that is automatically computed for an interface
with a manually configured address, refer to Configuring a
link-local IPv6 address on an interface.
