Re: [Kea-users] dhcp6 address assignment
I'm guessing you might need to use the flex_id hook library and define a flex-id to make that work? Though I don't really know as I have not looked into using the flex_id hook library myself. --Dan On Wed, Oct 19, 2022 at 4:09 PM Marek Greško via Kea-users < kea-users@lists.isc.org> wrote: > Hello, > > I have one more question on that topic.

Re: [Kea-users] isc group concept
Yes of course, I am aware of the include concept. So the group concept is definitely not here. I thought I missed something. I was using shell script generating global reservations from a table in a text file. Currently rewritten to generate separate include files for per subnet reservations. Since it is script generated I can put the options either as an include or as a list. Thanks for clarification.

[Kea-users] isc group concept
Hello, I was using ISC DHCP server and used the group concept to define common parameters for a group of clients. I found this concept very convenient. Is it possible to define something like group in the kea dhcp server reservations or should I define specific parameters to every host in reservations?

It would seem it is best to not use global reservations in your scenario: "This feature can be used to assign certain parameters, such as hostname or other dedicated, host-specific options. It can also be used to assign addresses or prefixes. However, global reservations that assign either of these bypass the whole topology determination provided by the DHCP logic implemented in Kea. It is very easy to misuse this feature and get a configuration that is inconsistent. To give a specific example, imagine a global reservation for the address 2001:db8:::1 and two subnets 2001:db8:::/48 and 2001:db8:::/48. If global reservations are used in both subnets and a device matching global host reservations visits part of the network that is covered by 2001:db8:::/48, it will get the IP address 2001:db8:::1, which is outside of the prefix announced by its local router using router advertisements. Such a configuration is unusable or, at the very least, riddled with issues, such as downlink traffic not reaching the device." https://kea.readthedocs.io/en/kea-2.2.0/arm/dhcp6-srv.html?highlight=global%20reservation#global-reservations-in-dhcpv6 > Thanks > Marek > --- Original Message --- > On Tuesday, October 18th, 2022 at 20:48, Dan Oachs wrote: >> Have you looked at using multiple reservations for the same IP?

Re: [Kea-users] dhcp6 address assignment
Hello, I run into another problems with this. To simplify the migration I use global reservations. I have two definitions for that machine. One for ethernet adapter and one for wifi adapter. Unfortunately the DUID is the same with both interfaces so the kea-dhcp6 cannot start with that configuration. ISC DHCPD6 hed no problem with that and everything was working correctly. It was because I was able to define both mac address and duid. Since I defined different value for mac for wifi there was no conflict. Probably the only one solution for this is to drop global reservations and switch to per subnet reservations?
