Network requirements

As shown in Figure 70, the network address prefix of DHCPv6 clients is 1::/64, and the IPv6 address of the DHCPv6 server is 2::2/64. The DHCPv6 client and server need to communicate via a DHCPv6 relay agent (Switch A).

Switch A acts as the gateway of network 1::/64. It sends RA messages to notify the hosts to obtain IPv6 addresses and other configuration parameters through DHCPv6.
