Configuration guidelines
When you configure automatic generation of an IPv6 link-local address for an interface, follow these
guidelines:
•
After an IPv6 global unicast address is configured for an interface, a link-local address is generated
automatically. The automatically generated link-local address is the same as the one generated by
using the ipv6 address auto link-local command. If a link-local address is manually assigned to an
interface, this manual link-local address takes effect. If the manually assigned link-local address is
removed, the automatically generated link-local address takes effect.
•
The undo ipv6 address auto link-local command can only remove the link-local addresses
generated through the ipv6 address auto link-local command. However, if an IPv6 global unicast
address is already configured for an interface, the interface still has a link-local address because
the system automatically generates one for the interface. If no IPv6 global unicast address is
configured, the interface has no link-local address.
