CCNA 200 301 Network Fundamentals

Explanation:
The “ipv6 address autoconfig” command causes the device to perform IPv6 stateless address auto-configuration to discover prefixes on the link and then to add the EUI-64 based addresses to the interface. Addresses are configured
depending on the prefixes received in Router Advertisement (RA) messages. The device will listen for RA messages which are transmitted periodically from the router (DHCP Server). This RA message allows a host to create a global IPv6
address from:

• Its interface identifier (EUI-64 address)
• Link Prefix (obtained via RA)

Note: Global address is the combination of Link Prefix and EUI-64 address
