Configuring Basic IPv6 Functions
Enabling IPv6
Before performing IPv6-related configurations, you need to enable IPv6. Otherwise, an interface cannot
forward IPv6 packets even if it has an IPv6 address configured.
Follow these steps to Enable IPv6:

Configuring an IPv6 Unicast Address
IPv6 site-local addresses and aggregatable global unicast addresses can be configured in the following
ways:
z
EUI-64 format: When the EUI-64 format is adopted, the IPv6 address prefix of an interface is the
configured prefix, and the interface identifier is generated automatically by the interface.
z
Manual configuration: IPv6 site-local addresses or aggregatable global unicast addresses are
configured manually.
z
Stateless address autoconfiguration: IPv6 global unicast addresses are generated automatically
based on the address prefix information contained in the RA message.
IPv6 link-local addresses can be configured in either of the following ways:
z
Automatic generation: The device automatically generates a link-local address for an interface
according to the link-local address prefix (FE80::/10) and the link-layer address of the interface.
z
Manual assignment: IPv6 link-local addresses can be assigned manually.
To avoid link-local address conflicts, it is recommended to use the automatic generation method.
