Description
Use the ipv6 dhcp server command to enable the DHCPv6 service on an interface.
When the rapid-commit keyword is configured, two-message interaction with a client is permitted
when address prefixes or other configuration is being allocated. If the Solicit packet from a client
contains the rapid-commit option, the DHCPv6 server will respond with a Reply message directly.
