-# DHCPv6 prefix delegation {#dhcp6_pd_doc}
-
-DHCPv6 prefix delegation client implementation is split between Control Plane and Data Plane.
-Data Plane can also be used alone by external application (external Control Plane) using Data Plane Binary API.
-
-Number of different IA\_PDs managed by VPP is currently limited to 1 (and corresponding IAID has value 1).
-Client ID is of type DUID-LLT (Link Layer address plus time) and is created on VPP startup from avaliable interfaces (or chosen at random for debugging purposes).
-Server ID is only visible to Data Plane. Control Plane identifies servers by a 32-bit handle (server\_index) mapped to Server ID by Data Plane.
-
-## Control Plane
-
-DHCPv6 PD clients are configured per interface.
-When configuring a PD client we have to choose a name of a prefix group for that client.
-Each prefix obtained through this client will be flagged as belonging to specified prefix group.
-The prefix groups are used as a filter by prefix consumers.
-
-To enable client on particular interface call Binary API function dhcp6\_pd\_client\_enable\_disable with param 'sw\_if\_index' set to that interface,
-'prefix\_group' set to prefix group name and 'enable' set to true.
-Format of corresponding Debug CLI command is: "dhcp6 pd client <interface> [disable]"
-
-To add/delete IPv6 address potentially using available prefix from specified prefix group call Binary API command ip6\_add\_del\_address\_using\_prefix with parameters:
-> sw\_if\_index - software interface index of interface to add/delete address to/from
-> prefix\_group - name of prefix group, prefix\_group[0] == '\0' means no prefix should be used
-> address - address or suffix to be used with a prefix from selected group
-> prefix\_length - subnet prefix for the address
-> is\_add - 1 for add, 0 for remove
-or Debug CLI command with format: "set ip6 addresses <interface> [prefix group <n>] <address> [del]"
-
-When no prefix is avaliable, no address is physically added, but is added once a prefix becomes avaliable.
-Address is removed when all available prefixes are removed.
-When a used prefix is removed and there is other available prefix, the address that used the prefix is reconfigured using the available prefix.
-
-There are three debug CLI commands (with no parameters) used to show the state of clients, prefixes and addresses:
- show ip6 pd clients
- show ip6 prefixes
- show ip6 addresses
-
-### Example configuration
-
-set int state GigabitEthernet0/8/0 up
-dhcp6 pd client GigabitEthernet0/8/0 prefix group my-dhcp6-pd-group
-set ip6 address GigabitEthernet0/8/0 prefix group my-dhcp6-pd-group ::7/64
-
-## Data Plane
-
-First API message to be called is dhcp6\_clients\_enable\_disable with enable parameter set to 1.
-It enables DHCPv6 client subsystem to receive UDP messages containing DHCPv6 client port (sets the router to DHCPv6 client mode).
-This is to ensure client subsystem gets the messages instead of DHCPv6 proxy subsystem.
-
-There is one common Binary API call for sending DHCPv6 client messages (dhcp6\_pd\_send\_client\_message) with these fields:
-> msg\_type - message type (e.g. Solicit)
-> sw\_if\_index - index of TX interface
-> server\_index - used to dentify DHCPv6 server,
- unique for each DHCPv6 server on the link,
- value obrtained from dhcp6\_pd\_reply\_event API message,
- use ~0 to send message to all DHCPv6 servers
-> param irt - initial retransmission time
-> param mrt - maximum retransmission time
-> param mrc - maximum retransmission count
-> param mrd - maximum retransmission duration for sending the message
-> stop - if non-zero then stop resending the message, otherwise start sending the message
-> T1 - value of T1 in IA\_PD option
-> T2 - value of T2 in IA\_PD option
-> prefixes - list of prefixes in IA\_PD option
-
-The message is automatically resent by Data Plane based on parameters 'irt', 'mrt', 'mrc' and 'mrd'.
-To stop the resending call the same function (same msg\_type is sufficient) with 'stop' set to 1.
-
-To subscribe for notifications of DHCPv6 messages from server call Binary API function
-want\_dhcp6\_pd\_reply\_events with enable\_disable set to 1
-Notification (dhcp6\_pd\_reply\_event) fileds are:
-> sw\_if\_index - index of RX interface
-> server\_index - used to dentify DHCPv6 server, unique for each DHCPv6 server on the link
-> msg\_type - message type
-> T1 - value of T1 in IA\_PD option
-> T2 - value of T2 in IA\_PD option
-> inner\_status\_code - value of status code inside IA\_PD option
-> status\_code - value of status code
-> preference - value of preference option in reply message
-> prefixes - list of prefixes in IA\_PD option
-
-Prefix is a struct with with these fields:
-> prefix - prefix bytes
-> prefix\_length - prefix length
-> valid\_time - valid lifetime
-> preferred\_time - preferred lifetime
