Dynamic IPv6 address assignment configurations example
Network requirements
As shown in Figure 73 , the switch serves as the DHCPv6 server. It assigns IPv6 addresses on subnet
1:2::/32 to clients Host A and Host B, and assigns IPv6 addresses on subnet 1:3::/32 to clients Host C
and Host D.
Configuration considerations
Configure the following settings on the DHCPv6 server:
1. Enable IPv6 and DHCPv6 server.
2. Configure IPv6 address 1:2::1/32 for interface VLAN-interface 2 that connects to Host A and Host
B, and configure IPv6 address 1:3::1/32 for interface VLAN-interface 3 that connects to Host C
and Host D.
3. Create DHCPv6 address pools, which contain subnets 1:2::/32 and 1:3::/32 respectively.
4. Enable the DHCPv6 server on the interfaces that connect to the clients.
