Re: [Kea-users] Hints
Hi Joshua, Looks like it might not be supported in 2.2.0. Here is a, now closed, GL issue discussing PD hints: https://gitlab.isc.org/isc-projects/kea/-/issues/1958 which was milestoned for 2.3.4. Indeed, I just found it in the release notes for 2.3.4: https://downloads.isc.org/isc/kea/2.3.4/Kea-2.3.4-ReleaseNotes.txt 4. **PD hints**: Kea now understands when a DHCPv6 client prefers a prefix of a certain length. If Kea is configured to hand out /64, /60, and /56 prefixes and the client requests /56, it will get it. Previously, Kea ignored the hint and assigned prefixes in the order the pools appeared in the config file [#1958]. 2.3.4 is part of the 2.3 development branch and is not recommended for production use. The next stable (2.4.0) will include this functionality and should be released this summer. Sorry to have misled you.

Re: [Kea-users] Hints
Joshua, Assuming the logging is correct, it looks like the hint may not be correct. It should be just an integer. It shouldn't have any other data (such as :: or /) in the field: https://www.rfc-editor.org/rfc/rfc8415#section-18.2.1 The client MAY include values in IA Prefix options (see Section 21.22) encapsulated within IA_PD options as hints for the delegated prefix and/or prefix length for which the client has a preference. See Section 18.2.4 for more on prefix-length hints. https://www.rfc-editor.org/rfc/rfc8415#section-21.22 prefix-lengthLength for this prefix in bits. A 1-octet unsigned integer. You could probably confirm the content of the field with a packet capture. Thank you, Darren Ankney On Tue, May 23, 2023 at 5:09 PM Joshua Pool wrote: > > Thanks for the response.

Re: [Kea-users] Hints
Thanks for the response. I am using a Mikrotik router and I can get the desired PD from Charter Spectrum just fine but when I try to do the same with Kea it always assigns me the delegated-len value of /56 regardless of what hint I include. In this example my Mikrotik is set with prefix hin ::/64 In Kea the DEBUG DHCP6 PACKET RECEIVED it shows the prefix=::/64 DEBUG DHCP6_PROCESS_IA_PD_REQUEST duid=[00:03:00:01:0e:21:15:70:0c:f0], tid=0x26e767: server is processing IA_PD option with iaid=1 and hint=:: DHCP6_PD_LEASE_ADVERT duid=[00:03:00:01:0e:21:15:70:0c:f0], tid=0xa0e83f: lease for prefix fd00:c40:20:600::/56 and iaid=1 will be advertised Full Log: 20:47:11 DEBUG DHCP6_PACKET_RECEIVED duid=[00:03:00:01:0e:21:15:70:0c:f0], tid=0xa0e83f: SOLICIT (type 1) received from fe80::c21:15ff:fe70:cf0 to ff02::1:2 on interface eth1 20:47:11 DEBUG DHCP6_PROCESS_IA_PD_REQUEST duid=[00:03:00:01:0e:21:15:70:0c:f0], tid=0xa0e83f: server is processing IA_PD option with iaid=1 and hint=:: 20:47:11 DEBUG DHCPSRV_MEMFILE_GET_IAID_DUID obtaining IPv6 leases for IAID 1 and DUID 00:03:00:01:0e:21:15:70:0c:f0 and lease type IA_PD 20:47:11 DEBUG ALLOC_ENGINE_V6_ALLOC_UNRESERVED no static reservations available - trying to dynamically allocate leases for client duid=[00:03:00:01:0e:21:15:70:0c:f0], tid=0xa0e83f 20:47:11 DEBUG HOSTS_CFG_GET_ONE_SUBNET_ID_ADDRESS6 get one host with reservation for subnet id 1 and having IPv6 address fd00:c40:20:600:: 20:47:11 DEBUG HOSTS_CFG_GET_ALL_SUBNET_ID_ADDRESS6 get all hosts with reservations for subnet id 1 and IPv6 address fd00:c40:20:600:: 20:47:11 DEBUG HOSTS_CFG_GET_ALL_SUBNET_ID_ADDRESS6_COUNT using subnet id 1 and address fd00:c40:20:600::, found 0 host(s) 20:47:11 DEBUG HOSTS_CFG_GET_ONE_SUBNET_ID_ADDRESS6_NULL host not found using subnet id 1 and address fd00:c40:20:600:: 20:47:11 DEBUG DHCPSRV_MEMFILE_GET_ADDR6 obtaining IPv6 lease for address fd00:c40:20:600:: and lease type IA_PD 20:47:11 INFO DHCP6_PD_LEASE_ADVERT duid=[00:03:00:01:0e:21:15:70:0c:f0], tid=0xa0e83f: lease for prefix fd00:c40:20:600::/56 and iaid=1 will be advertised Any Thoughts?

Re: [Kea-users] Hints
Hello Joshua, It would appear it just happens. No need to configure anything. There is a debug message about the hint being processed: https://kea.readthedocs.io/en/kea-2.2.0/kea-messages.html DHCP6_PROCESS_IA_PD_REQUEST %1: server is processing IA_PD option with iaid=%2 and hint=%3 This is a debug message that indicates a processing of received IA_PD option. The first argument contains the client and the transaction identification information. The second argument holds the IAID of the IA_PD option. The third argument may hold the hint for the server about the prefix that the client would like to have allocated. If there is no hint, the argument should provide the text indicating that the hint hasn't been sent.
