Which command automatically generates an IPv6 address from a specified (CCNA 200-301)
Which command automatically generates an IPv6 address from a specified IPv6 prefix and MAC address of an interface?
A) ipv6 address dhcp.
B) ipv6 address 2001:DB8:5:112::/64 eui-64.
C) ipv6 address autoconfig.
D) ipv6 address 2001:DB8:5:112::2/64 link-local.
Solution
Correct answer: B) ipv6 address 2001:DB8:5:112::/64 eui-64.
The "ipv6 address" command with the "eui-64" option is used to automatically generate an IPv6 address based on the specified IPv6 prefix and the MAC address of an interface. EUI-64 (Extended Unique Identifier-64) is a method that involves incorporating the 48-bit MAC address of the interface into the IPv6 address, creating a 64-bit interface identifier. This process is commonly used for Stateless Address Autoconfiguration (SLAAC) in IPv6 networks.
