Basic Introduction to IPv6 (2)-IPv6 address configuration method

Basic Introduction to IPv6 (2) -- how to configure IPv6 addresses? IPv6 address = prefix + Interface ID prefix: equivalent to the network ID Interface ID in the IPv4 address: equivalent to the host ID in the IPv4 address l manual configuration: You can set an Ipv6 address through static interface; l automatic stateful Address Configuration (DHCPV6): it means that the DHCP server manages the IPv6 address and other information (such as DNS) from the address pool of the DHCP server ), the DHCP server allocates a complete IPv6 address from the address pool to the client host. l The Stateless Address is automatically configured (radvd): DHCP server is not required for management, the client obtains an IPv6 address prefix based on the network RA (route notice), and then calculates its own interface ID based on its MAC address, you can obtain a complete IPv6 address by prefix + id. They generally use a DHCP server to obtain the address of the DNS server .? Get the prefix? Interface ID generation-IEEE EUI-64 specification: converting a 48-bit MAC address into a 64bit Interface ID? Duplicate address detection (DAD) is also known as the M/O flag that is closely related to address allocation. When set to 1, this flag indicates that the host uses the configuration protocol to obtain a stateful address. The implication is that when the flag is set to 1, DHCPV6 is used to allocate the address; when the flag is set to 0, stateless (RADVD) is used) other stateful configuration tags, also known as O tags. When set to 1, this flag indicates that the host uses the configuration protocol to obtain other configuration settings. For other configuration information, we can simply resolve it to DNS or SIP server information other than IP addresses. When this flag is set to 1, it indicates that the configuration information except the address should be obtained from the DHCPV6 server; when this flag is set to 0, it indicates that the configuration information except the address should be extracted from RADVD;
