2022-09-21dhcpv6-pd: T2821: bugfix Jinja2 template - missing conditional ifChristian Poessinger
Specifying "dhcpv6-options pd 0" for any interface without an interface where we delegate an address to resulted in a commit error: {% for interface, interface_config in pd_config.interface.items() if pd_config.interface is vyos_defined %} jinja2.exceptions.UndefinedError: 'dict object' has no attribute 'interface'

The hedadecimal option dhcp-cliend-identifier format is required to set values without quotes, separated by colons.
2021-04-02interfaces: dhcp-client: T3454: add reject optionCharles Surett
Sometimes a modem might give a local IP before it retrieves a WAN IP. This can be an issue with failover routes, since the default route will get overridden.

2020-11-07interfaces: dhcp-client: T2997: add option to not request DHCP router addressChristian Poessinger
Some might want to have an IP address handed out by a DHCP server but not want a default route to be installed. This can be done using the CLI command: "set interfaces ethernet eth2 dhcp-options no-default-route"
2020-08-23dhcpv6-pd: T2677: add support for rapid-commit optionChristian Poessinger
When rapid-commit is specified, dhcp6c will include a rapid-commit option in solicit messages and wait for an immediate reply instead of advertisements.
2020-08-23dhcpv6-pd: T2821: support dhcpv6-pd without "address dhcpv6"Christian Poessinger
Currently DHCPv6-PD requires an interface address configured to dhcpv6 on the CLI. This is not required also sometimes there is either no dhcpv6 interface addressing available (PPPoE) or wanted. This limitation was artificial due to the old interface code. Change the implementation to spawn the DHCPv6 client and request a prefix even when there is no address request configured.
2020-08-22dhcpv6-pd: T2677: optimize CLI interface for PD configurationChristian Poessinger
The current CLI did not support multiple prefix-delegations per interface. 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.

2020-08-14templates: dhcp-client: fix "Autogenerated by" script nameChristian Pössinger
Commit 21bc98f1 ("ifconfig: dhcp: T2767: client must not start when interface is disabled") dropped dhcp.py which is now directly handled by interface.py. This change should also be reflected in the generated files.
2020-08-03ifconfig: T2653: unify DHCPv4 configurationChristian Poessinger
Pass the interface dictionary transparently to the DHCP module and render the DHCP client config template directly from the same source instead of transcoding it once more.
2020-08-03ifconfig: T2740: pass config dict to DHCP class for IPv6Christian Poessinger
This removes additional code paths as we can instatly work with the input dict the same was as it was done for PPPoE. This fixes the entire DHCPv6-PD support on non PPPoE interfaces as this was lost in translation while processing T2653.

2020-05-26dhcpv6-pd: T2506: add option to request specific prefix lengthChristian Poessinger
Some ISPs (e.g. Comcast) only delegate a /64 by default. You have to explicitly "ask" for a bigger (e.g. /60) prefix. This commit adds a CLI node to request a specific prefix length in the range 32 - 64. dhcpv6-options { prefix-delegation { length 60 } }
2020-05-26dhcpv6-pd: pppoe: T2506: restructure CLIChristian Poessinger
Rename the CLI nodes for prefix delegation from "dhcpv6-options delegate <interface>" to "dhcpv6-options prefix-delegation interface <interface>". The change is required to add the possibility to request for specific prefix sized via the CLI. That option was not possible with the old configuration tree.

2020-05-17pppoe: dhcpv6-pd: T421: initial supportChristian Poessinger
The following configuration will assign a /64 prefix out of a /56 delegation to eth0. The IPv6 address assigned to eth0 will be <prefix>::ffff/64. If you do not know the prefix size delegated to you, start with sla-len 0. pppoe pppoe0 { authentication { password vyos user vyos } description sadfas dhcpv6-options { delegate eth0 { interface-id 65535 sla-id 0 sla-len 8 } } ipv6 { address { autoconf } enable } source-interface eth1 } vyos@vyos:~$ show interfaces Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down Interface IP Address S/L Description --------- ---------- --- ----------- eth0 2001:db8:8003:400::ffff/64 u/u
2020-05-17dhcpv6-pd: T421: migrate from ISC dhclient to wide-dhcpv6-clientChristian Poessinger
ISC does not support running the client on PPP(oE) interfaces which makes it unusable for DHCPv6 Prefix Delegation tasks.

2020-04-28dhclient: T2393: remove intermediate _DHCP helper classChristian Poessinger
The intermedite class only held the path to the configuration files - thus its existence was doubtworthy. For better readability and a clean inheritance graph that class has been dropped.
