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-lifetime 600 preferred-lifetime 400
console(config-dhcp6s-pool)#exit
3 Configure the DHCPv6 server functionality on VLAN 200 and specify the
pool to use for DHCPv6 clients.
console(config)#interface vlan 200
console(config-if-vlan200)#ipv6 dhcp server my-pool2

Configuring an Interface as a DHCPv6 Relay Agent
This example configures a VLAN routing interface as a DHCPv6 Relay. The
command defines the destination address of the relay server and the interface
used for reachability to the relay server.
To configure the switch:
