Example: Configuring dynamic IPv6 address assignment
Network configuration
As shown in Figure 73, Switch 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 Switch A, configure the IPv6 address 1::1:0:0:1/96 for VLAN-interface 10 and 1::2:0:0:1/96 for
VLAN-interface 20. 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 suffix 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.
