Dynamic IPv6 address assignment configuration example
Network requirements
As shown in Figure 102, Router A acts as a DHCPv6 server to assign IPv6 addresses to the clients
on subnets 1::1:0:0:0/96 and 1::2:0:0:0/96.
On Router A, configure the IPv6 address 1::1:0:0:1/96 for GigabitEthernet 2/0/1 and 1::2:0:0:1/96 for
GigabitEthernet 2/0/2. The lease duration of the addresses on subnet 1::1:0:0:0/96 is 172800
seconds (two days), the valid time is 345600 seconds (four days), the domain name is aabbcc.com,
and the DNS server address is 1::1:0:0:2/96. The lease duration of the addresses on subnet
1::2:0:0:0/96 is 432000 seconds (five days), the valid time is 864000 seconds (ten days), the domain
name is aabbcc.com, and the DNS server address is 1::2:0:0:2/96.
