Network requirements
As shown in
793H
Figure 57 , Switch A serves as a DHCPv6 server to assign IPv6 addresses to the clients in
subnets 1::1:0:0:0/96 and 1::2:0:0:0/96. On Switch A, configure the IPv6 address 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.
