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.
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:
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:
