The user host usesDHCP message to request a leased IP address and to obtain information about other settings. . The server replies, assigning the address to the host and informing the host of the other settings it wants. The most significant difference between DHCPV4 and stateful DHCPv6 is that a stateful DHCPv6 server does not provide a default routeThe host information. Instead, the built-in NDP protocol lets the host request the local router for self-identification. In addition, the host uses the same information as the DHCPV4 Totalphysically identical processes. Figure 16-5 compares what hosts can learn using DHCPv4 and stateful DHCPv6.If the stateful DHCPv6 server is on a different subnet than the host, then DHCPv6 enables the DHCPv6 Relay Agent feature, as shown in Figure 16-6. For example, on the left side of the figure, Host A sends a DHCPv6 Solicit message to begin trying to learn about an address it wants to use. The message is delivered to the IPv6 multicast destination address (FF02::l:2) o The router (for example, R1) will not forward packets sent to that local range multicast address. However, by adding a DHCPv6 relay agent configuration to R1's G0/0 interface (as shown in Figure 16-6), R1 forwards DHCPv6 messages from host A to the DHCP server.ipv6 dhcp relay destination 2001:db8:1111:3::8f1 - to FF02::1:2 I T - to 2001:DB8: 1---------- local link from A >--------- from 2001:DB8:1111:2::1Figure 16-6 DHCPv6 Relay Agent and DHCPIPv6 AddressesStateless address autoconfiguration
