[Sysname] interface Vlan-interface 1
[Sysname-Vlan-interface1] ipv6 address 3001::/64 eui-64
ipv6 address link-local
Syntax
ipv6 address ipv6-address link-local
undo ipv6 address ipv6-address link-local
View
VLAN interface view
Parameters
ipv6-address: IPv6 link-local address. The first ten bits of an address must be 1111111010 (binary), that
is, the first group of hexadecimals in the address must be FE80 to FEBF.
Description
Use the ipv6 address link-local command to configure a link-local address manually for a specified
interface.
Use the undo ipv6 address link-local command to remove the configured link-local address for an
interface.
Note that:
Manual assignment takes precedence over automatic generation. That is, if you first adopt automatic
generation and then manual assignment, the manually assigned link-local address will overwrite the
automatically generated one. If you first adopt manual assignment and then automatic generation, the
automatically generated link-local address will not take effect and the link-local address of an interface
is still the manually assigned one. If you delete the manually assigned address, the automatically
generated link-local address is validated. For automatic generation of an IPv6 link-local address, refer
to the ipv6 address auto link-local command.
