IPv6 Basics
Configuration Task
List
Complete the following tasks to perform IPv6 basics configuration:
Configuring Basic IPv6
Functions
Enabling the IPv6 Packet
Forwarding Function
Before IPv6-related configurations, you must 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:
Configuring an IPv6
Unicast Address
IPv6 site-local addresses and aggregatable global unicast addresses can be
configured in the following ways:
