Configuring Basic IPv6
Functions
Enabling the IPv6 Packet
Forwarding Function
Configuring an IPv6
Unicast Address
Before IPv6-related configurations, you need to enable the IPv6 packet forwarding
function. Otherwise, an interface cannot forward IPv6 packets even if an IPv6
address is configured, resulting in communication failures in the IPv6 network.
Follow these steps to enable the IPv6 packet forwarding function:
To do...
Enter system view
Enable the IPv6 packet
forwarding function
IPv6 site-local addresses and aggregatable global unicast addresses can be
configured in either of the following ways:
EUI-64 format: When the EUI-64 format is adopted to form IPv6 addresses, the
■
IPv6 address prefix of an interface is the configured prefix, and the interface
identifier is derived from the link-layer address of the interface.
Manual configuration: IPv6 site-local addresses or aggregatable global unicast
■
addresses are configured manually.
IPv6 link-local addresses can be configured in either of the following ways:
Automatic generation: The device automatically generates a link-local address
■
for an interface according to the link-local address prefix (FE80::/64) and the
link-layer address of the interface.
Manual assignment: IPv6 link-local addresses can be assigned manually.
