Dynamic IPv6 address and prefix assignment configuration
example
Network requirements
As shown in Figure 376, Firewall A serves as a DHCPv6 server, and assigns an IPv6 prefix, DNS server
address, domain name suffix, SIP server address, and SIP server domain name to the DHCPv6 client,
Firewall B. 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.
With the configuration obtained from Firewall A, Firewall B serves as a DHCPv6 server and assigns IP
prefixes in the range of 12:34::/48 to 12:34:FFFF::/48 and addresses in the subnet 12:34:56::/48 to
Router A and Router B.
Configuration considerations
• To configure Firewall A:
a. Enable IPv6.
b. Enable the DHCPv6 server.
c. Create a prefix pool.
d. Create an address pool, and specify a prefix pool so that Firewall A can assign a prefix to
Firewall B.
e. Enable the DHCPv6 server on GigabitEthernet 0/1 that connects to Firewall B.
• To configure Firewall B that serves as the DHCPv6 client:
f. Enable IPv6.
g. Configure interface GigabitEthernet 0/2 to use DHCPv6 for IPv6 prefix acquisition, and
specify the prefix ID as 1 and option group ID as 1.
