Last week I participated #SaltSprint to discuss declarative network configuration in #NixOS. I got the feedback, that replacing scripted networking with #ifstate of a full blown frr-based EVPN setup is possible and did just work. 💪
This feedback makes me really happy 🤗 #WorksAsIntended
In return, ifstate got a larger pull request improving its python packaging and CI tooling. And there is a commitment for further contributions. ❤️ ❤️ ❤️

2) IPv6 tokenized interface identifier support was added to allow to configure the IPv6 interface identifier for interfaces doing SLAAC: https://ifstate.net/schema/2.4/#interfaces_pattern1_token
This was specified in https://datatracker.ietf.org/doc/html/draft-chown-6man-tokenised-ipv6-identifiers-02 and is implemented in the Linux kernel. Ifstate provides the same functionality as the ip-token(8) command from iproute2.
The new release is already available in Alpine Linux edge and will be part of Alpine Linux 3.24 🥳

#ifstate 2.4.0 - a tool for declarative network configuration for Linux - was released:
https://codeberg.org/routerkit/ifstate/releases/tag/2.4.0This is release contains two new major features:
1) When no MAC address was specified in the config, the L2 address of virtual ifaces are now build reproducible. The SHAKE256 cryptographic hash function is used with a machine-id+netns+ifname dependent input string: https://ifstate.net/2.4/docs/macaddr/
Physical ifaces are set to their permanent MAC addresses.

In case you bother why I'm looking at MAC address handling for various link types of the Linux kernel: I'm working on a new ifstate feature to get reproducible mac addresses for virtual interfaces and reset the mac address of physical links to their permanent mac address by default.
https://codeberg.org/routerkit/ifstate/pulls/185
The reproducible MAC addresses are based on SHAKE256 with an input build from the host (machine-id), netns and interface (link) name.

The ifstate git repository on #Codeberg has been moved from my personal account into the RouterKit project at https://codeberg.org/routerkit/ifstate
With moving the project it gains access to CI/CD runners and the first step is to use them to provide #Debian packages from the upcoming 2.2.4 release 🥳
https://codeberg.org/routerkit/-/packages/debian/ifstate/I already use it in prod for haproxy setups on Debian trixie using different network namespaces for listeners and server access.

I don't like to maintain packaging upstream, but… I required netns configuration support on Debian for using network namespaces with haproxy!
Sadly I had to use dh_virtualenv because pyroute2 in Debian sid+stable is to old to have all required netns related features.
Haproxy has namespace support for listeners and servers which allows one to easily build multi-tenant load-balancing setups. 😎

The ifstate 2.2 release - a tool for declarative network configuration for Linux - is available in the most recent stable releases of Alpine Linux 3.23 and NixOS 25.11. 🥳
Fun fact: this is the first NixOS release where you can use a declarative network configuration out of the box 😉
