Configuration guidelines

When you configure VLAN interfaces, follow these guidelines:
• A link-local address is automatically generated for an IPv6 VLAN interface after an IPv6 site-local
address or global unicast address is configured for the VLAN interface. This generated link-local
address is the same as the one generated in the Auto mode. If a manually assigned link-local
address is available, the manually assigned one takes effect. After the manually assigned link-local
address is removed, the automatically generated one takes effect.
For an IPv6 VLAN interface whose IPv6 link-local address is generated automatically after you
•
assign an IPv6 site-local address or global unicast address, removing the IPv6 site-local address or
global unicast address also removes the generated IPv6 link-local address.
For IPv6 link-local address configuration, manual assignment takes precedence over automatic
•
generation. If you first adopt the manual assignment and then the automatic generation, the
automatically generated link-local address will not take effect and the link-local address of the
interface is still the manually assigned one. However, if you remove the manually assigned one, the
one automatically generated takes effect.
