Network requirements
As shown in Figure 373, the firewall serves as a DHCPv6 server, and assigns the IPv6 prefix, DNS server
address, domain name suffix, SIP server address, and SIP server domain name to the DHCPv6 clients.
The IPv6 address of the router is 1::1/64.
The firewall assigns prefix 2001:0410:0201::/48 to the client whose DUID is
00030001CA0006A40000, and assigns prefixes ranging from 2001:0410::/48 to
2001:0410:FFFF::/48 (excluding 2001:0410:0201::/48) to other clients. The DNS server address is
2::2:3. The domain name suffix is aaa.com. The SIP server address is 2:2::4, and the domain name of
the SIP server is bbb.com.
Configuration considerations
• Enable IPv6 and DHCPv6 server.
• Create a prefix pool containing prefix 2001:0410::/32 with the length of the assigned prefix being
48, so that the server assigns clients the prefixes ranging from 2001:0410::/48 to
2001:0410:FFFF::/48.
• Create an address pool. Configure a static prefix in the address pool and have the prefix pool
referenced by the address pool. Configure other configuration parameters.
• Enable the DHCPv6 server on the interface that connects to the clients and apply the address pool
to the interface.
