1082 Configuring DHCPv6 Server and Relay Settings
4
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:
1
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
2
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 
00:01:00:09:f8:79:4e:00:04:76:73:43:76 valid-
lifetime 600 preferred-lifetime 400
console(config-dhcp6s-pool)#prefix-delegation 
2001:DB8:1001::/32 
00:01:00:09:f8:79:4e:00:04:76:73:43:76 valid-
lifetime 600 preferred-lifetime 400
console(config-dhcp6s-pool)#prefix-delegation 
2001:DB8:1002::/32 
00:01:00:09:f8:79:4e:00:04:76:73:43:76 valid-
