Configuring a Link-local Address for an Interface

Link-local addresses are used in neighbor discovery and in the communication between nodes on the local link during stateless address autoconfiguration. Link-local addresses are valid only on local links, meaning that packets with link-local addresses as source or destination addresses are not forwarded to other links.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface view is displayed.
Run ipv6 enable
IPv6 is enabled on the interface.
Perform either of the following operations according to on-site requirements:
- To automatically configure the link-local address of the interface, run the ipv6 address auto link-local command.
- To manually configure the link-local address of the interface, run the ipv6 address ipv6-address link-local command.
You can configure multiple IPv6 addresses but only one link-local address for an interface.
Run commit
The configuration is committed.
