DHCPv6 server configuration examples Dynamic IPv6 prefix assignment configuration example Network requirements As shown in Figure 65, Switch serves as a DHCPv6 server to assign the IPv6 prefix, DNS server address, domain name, SIP server address, and SIP server name to each DHCPv6 client. The switch 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 DHCPv6 clients reside in domain aaa.com. The SIP server address is 2:2::4, and the SIP server name is bbb.com.
