DHCPv6 Address Assignment

The use of DHCPv6 is not required for IPv6 client connectivity if SLAAC is already deployed. There are two modes of 
operation for DHCPv6 called Stateless and Stateful. 

The DHCPv6 Stateless mode is used to provide clients with additional network information not available in the router 
advertisement. This information can include the DNS domain name, DNS server(s), and other vendor-specific options. 
The following interface configuration example is for an IPv6 router implementing stateless DHCPv6 with SLAAC enabled:

interface Vlan20

 description IPv6-DHCP-Stateless

 ip address 192.168.20.1 255.255.255.0

 ipv6 enable

 ipv6 address 2001:DB8:0:20::1/64

 ipv6 nd other-config-flag

 ipv6 dhcp relay destination 2001:DB8:0:20::100

end

The DHCPv6 Stateful mode operates similar to DHCPv4, that is, it assigns addresses to each client instead of the client 
generating the address as in SLAAC. The following interface configuration is for an IPv6 router implementing stateful 
DHCPv6 with SLAAC turned off:

interface Vlan20

 description IPv6-DHCP-Stateful

 ip address 192.168.20.1 255.255.255.0

 ipv6 enable

 ipv6 address 2001:DB8:0:20::1/64

 ipv6 nd prefix 2001:DB8:0:20::/64 no-advertise

 ipv6 nd managed-config-flag

 ipv6 nd other-config-flag

 ipv6 dhcp relay destination 2001:DB8:0:20::100
