To do so, you need to disable IRF fabric on all IRF fabric ports.z IPv6 unicast addresses can be configured for only one VLAN interface on an H3C S5600 Ethernetswitch. The total number of global unicast addresses and site-local addresses on the VLANinterface can be up to four.z After an IPv6 site-local address or global unicast address is configured for an interface, a link-localaddress will be generated automatically. The automatically generated link-local address is thesame as the one generated by using the ipv6 address auto link-local command.z The manual assignment takes precedence over the automatic generation. That is, if you first adoptthe automatic generation and then the manual assignment, the manually assigned link-localaddress will overwrite the automatically generated one. If you first adopt the manual assignmentand then the automatic generation, the automatically generated link-local address will not takeeffect and the link-local address of an interface is still the manually assigned one. If the manuallyassigned link-local address is deleted, the automatically generated link-local address takes effect.z You must have carried out the ipv6 address auto link-local command before you carry out theundo ipv6 address auto link-local command. However, if an IPv6 site-local address or globalunicast address is already configured for an interface, the interface still has a link-local addressbecause the system automatically generates one for the interface. If no IPv6 site-local address orglobal unicast address is configured, the interface has no link-local address.
