Some ISPs only send one /64 to a client per prefix-delegation request, but they allow the customer to request multiple prefixes. The 'dhcpv6-options prefix-delegation' node has been renamed and converted to a tag node named 'dhcpv6-options pd'. The tag node specifies a PD request (>=0). In the past the user needed to know what prefix will be assigned and required to calculate the sla-len by himself. The 'sla-len' node was dropped and is now calculated in the background from the 'dhcpv6-options pd 0 length' node. It is no longer mandatory to supply the 'sla-id' node, if sla-id is not specified it is 'guessed' by counting upwards. Example configuration: ---------------------- ethernet eth1 { address dhcpv6 dhcpv6-options { pd 0 { length 56 interface eth2 { address 1 } } } } This will request a /56 assignment from the ISP and will delegate a /64 network to interface eth2. VyOS will use the interface address ::1 on the delegate interface (eth2) as its local address.
