[SOLVED] VLANs: bare setup, no firewall, and yet, no ping.

[Sheelyuu]

Here it goes.
On a node, took one of the bridges, made it vlan-aware.
Took two basic debian bookworm lxc containers, on the same node, made their ip static xx.xx.xx.2 and xx.xx.xx.3 on that bridge, with the same VLAN tag, and no firewall.
Started them, checked with ip a that they well had their ip, made them ping themselves, works, made them ping each other, nothing.

I was trying to do something else on an other node, but when nothing worked, I devolved to testing the very simplest thing I assumed would work, and it didn't.
Am I sleep deprived (yes) and missing something?

Rebooted a single node. No change on it.

Rebooted the whole cluster. Stuff works.



Maybe has to do that sometimes node updates are scattered across weeks, and that with the changes to networking it got a bit derpy? No clue. Time for a coffee.
