The process of obtaining an IPv6 address by an IPv6 host through SLAAC begins with the generation of an LLAO Host A generates an LLA using the EUI-64 method: FF80::22FF:FEll:llllloOnce the LLA is generated, Host A has local link IPv6 connectivity. An RS message can then be sent, hoping to obtain the network prefix and prefix length information for the IPv6 public unicast address from the router on the local link.Step 3. After receiving the RS message from Host A, R1 replies with an RA message containing the network prefix and prefix length information for the IPv6 public unicast address: 2345::/64.Step 4. Host A generates its own IPv6 public unicast address, 2345::22FF:FE11:111lo, based on the information contained in the RA message. Before enabling this IPv6 address, Host A must also perform a DAD to detect whether there are other devices on the local link with the same address. Host A sends an NS message asking if any devices are using the IPv6 address 2345::22FF:FE11:11111OStep 5. Because no response is received after the NS message is sent, Host A concludes that this machine is the only device on the local link using the IPv6 address 2345::22FF:FE11:111, and Host A's SLAAC configuration terminates.The fourth address assignment method described in this section is the stateful DHCPv6 address assignment method. As with many other protocols, theDHCP also has a new version one for IPv6, DHCP version 6ODHCPv6 uses UDP as the transport protocol, and the DHCP clientDHCP clients and DHCP server relay devices use UDP port numbers 546 and 547 respectively. DHCPV6 is divided into the following two modes of operation. Stateful DHCPV6: The operation is quite similar to DHCPv4, where the DHCP server assigns IP addresses to DHCP clients and provides other network configuration information. The DHCP server maintains information about the association of the leased IP address with the DHCP client. Unlike DHCPv4, a stateful DHCPv6 server does not provide information related to default routes; the relevant information is provided by the NDP.94 Chapter 1 Network Protocols and Network Device Basicsthat is, all data received is processed, the cache is re-released, and the window size is left unchanged. However, if for some reason the TCP receiver is unable to process the data in the cache in a timely manner, it reduces the window size while informing the TCP sender. Take Figure
