Configuring DHCPv6 Server and Relay Settings
Configure the DHCPv6 server functionality on VLAN 100. Clients can use 
the preference value to determine which DHCPv6 server to use when 
multiple servers exist.
console(config-if-vlan100)#ipv6 dhcp server my-
pool preference 10
console(config-if-vlan100)#ipv6 nd other-config-
flag
console(config-if-vlan100)#exit
Configuring the DHCPv6 Server for Prefix Delegation
In this example, VLAN routing interface 200 is configured to delegate specific 
prefixes to certain DHCPv6 clients. The prefix-to-DUID mapping is defined 
within the DHCPv6 pool. 
To configure the switch:
Create the DHCPv6 pool and specify the domain name and DNS server 
information.
console(config)#ipv6 dhcp pool my-pool2
console(config-dhcp6s-pool)#domain-name dell.com
console(config-dhcp6s-pool)#dns-server 
2001:DB8:A328:22C::1
Specify the prefix delegations for specific clients. The first two commands 
provide multiple prefixes to the same client.
console(config-dhcp6s-pool)#prefix-delegation 
2001:DB8:1000::/32
