Ultimately I disagreed with the solution to use a separate parameter for IPv6, for the following reasons: - We can only have one local tunnel IP, so having two parameters means we need to check if the other one has been set (since setting both would be invalid) - There are already other cases in ifupdown2 which do ip.version == 6 including common parameters like address and gateway, and most parameters do take both IPv4 and IPv6 addresses (such as the remoteip field in vxlan), so having one parameter for both families would be consistent with other parameters in the interfaces file which take both families (regardless of the kernel implementation having two fields instead of one in this case) - ifupdown-ng already solved this problem using a single parameter instead of two, so doing something else would diverge ifupdown2 vs ifupdown-ng syntax which should be the same I could add additional error checking to ensure that remoteip[] and localip are the same address family if you’d like. Currently that results in a Netlink exception which gets passed back as an error message. The kernel only allows one address family for a vxlan interface.

Ultimately I disagreed with the solution to use a separate parameter for IPv6, for the following reasons: - We can only have one local tunnel IP, so having two parameters means we need to check if the other one has been set (since setting both would be invalid) - There are already other cases in ifupdown2 which do ip.version == 6 including common parameters like address and gateway, and most parameters do take both IPv4 and IPv6 addresses (such as the remoteip field in vxlan), so having one parameter for both families would be consistent with other parameters in the interfaces file which take both families (regardless of the kernel implementation having two fields instead of one in this case) - ifupdown-ng already solved this problem using a single parameter instead of two, so doing something else would diverge ifupdown2 vs ifupdown-ng syntax which should be the same I could add additional error checking to ensure that remoteip[] and localip are the same address family if you’d like. Currently that results in a Netlink exception which gets passed back as an error message. The kernel only allows one address family for a vxlan interface.

Not a big deal. yes, it seems a bit tricky, since we'd have to predict what ifupdown2 is doing - but with the current speed of ifupdown2 development, I'm not sure if VXLAN IPv6 support will land anytime soon. There's a similar PR open though in the ifupdown2 github [1]. Since there is currently discussion about moving away from ifupdown2 on debian-devel [2] [3] and the point of contention is not really about IF they will be moving away from ifupdown2 but rather WHAT the replacement will be, we could support our implementation (with possible compatibility patches) while we move to a new network stack. > BTW, I don't have followed the ifupdown-ng project since a long time. > (just follow the early days).

Judging from the current discussion on debian-devel, ifupdown-ng doesn't seem to be a candidate for the Debian network stack moving forward. There's some heated discussion between netplan and systemd-networkd, with some (from my perception) preference for systemd-networkd so we'll be monitoring that closely for our trixie release. I'll test this series a bit this week and report back. Would you be interested in sending a v2 afterwards? (particularly wrt to the perl style issues). Otherwise I can also take this patch series over. in any case, have you signed a CLA with us already? Otherwise we cannot include your patches in our repositories.
