 hexa (clat on linux when) | oh | 01:04:54 |
| hexa (clat on linux when) | silly me | 01:04:57 |
| hexa (clat on linux when) | you need to configure networkConfig.Bond = "lan" in .network files, not .netdev | 01:05:16 |

| hexa (clat on linux when) | nvm, you have that | 01:06:02 |
| hexa (clat on linux when) | the long codeblock is super annoying to consume | 01:06:13 |
| kdn | yeah, was about to post a screenshot ther | 01:06:36 |
| kdn | * yeah, was about to post a screenshot there | 01:06:38 |
| hexa (clat on linux when) | networkctl status lan | 01:07:02 |
| kdn |

| kdn | that last line seems like a clue | 01:08:10 |
| kdn | I remember it being some error before I correctly set up /etc/machine-id | 01:08:34 |
| hexa (clat on linux when) | it might need the machine-id for the duid | 01:08:55 |
| hexa (clat on linux when) | journalctl -u systemd-networkd | grep lan | 01:09:13 |
| kdn | that's more info that I can copy, but seems like the DHCPv4 address was removed for some reason | 01:11:09 |
| kdn |

| hexa (clat on linux when) | yeah, but's that is the most likely place to hold a clue | 01:11:32 |
| hexa (clat on linux when) | you will need to dig through that 🙂 | 01:11:51 |
| kdn | last 2 lines seem like a clue | 01:13:11 |
| kdn | IPv6LL is not configured yet | 01:13:40 |
| kdn | also /accept_ra' to '0' is suspicious, I did set networkConfig.IPv6AcceptRA = true | 01:14:33 |
| kdn | ooooh:
https://www.freedesktop.org/software/systemd/man/latest/systemd.network.html#IPv6AcceptRA=
This cannot be enabled on devices aggregated in a bond device, or when IPv6 link-local addressing (see LinkLocalAddressing=) or multicasting (see Multicast=) is disabled. Note, multicasting is disabled by default for some configurations, e.g. bridge ports. Hence, in that case Multicast= needs to be explicitly enabled to make this feature usable. When IPv6SendRA=, IPv6Forwarding=, or IPMasquerade= is enabled, this feature is disabled by default, but can be overridden by explicitly enabling this setting. Note, IPv6Forwarding= may be indirectly enabled when the global setting with the same name is enabled, or when IPMasquerade= is enabled on any other interfaces. See also IPv6Forwarding= and IPMasquerade= for more details. Enabled by default otherwise.

| hexa (clat on linux when) | you cannot enable it on enslaved links | 01:23:02 |
| hexa (clat on linux when) | you can enable it on the bonding interface | 01:23:19 |
| kdn | I seem to do that | 01:23:36 |
| kdn | maybe it's linkConfig.Multicast=true that's missing | 01:26:40 |
| kdn | 🎉 this is the one thing missing, wondering why it's not required on the bridge interface | 01:28:22 |
| kdn | this helped resolve the issue https://github.com/nazarewk-iac/nix-configs/commit/b4f7d51ed8429d0cd404bf117a4cb0ee6ebe98c3 | 01:31:05 |
| hexa (clat on linux when) | because linux bridges are multicast queriers | 01:31:50 |
| hexa (clat on linux when) | they aggregate many unicast links and can fan out multicast | 01:32:04 |
