So I’ve installed the snapshot version of OWRT on a Velop (whw01) I noticed I have a single interface LAN but it is curiously also named br-lan. It contains eth0, eth1, eth2. So I’d like to sliver these eth1, eth2 off the bridge and into their own interfaces. And I’d like to make the radios their own too. The intended purpose of the Velop is to face the internet as a router so I don’t want bridges. I’ve tried making the interfaces manually, but they don’t work. I understand the logic of making an interface and then adding devices (eth1, etc) to it.
So in OWRT land, is the br-xxx just the way the software is? Similarly to enable the radios, one should be able to follow the same steps?
Also what is eth0 used for?
In most cases, a bridge interface is needed - both to 'merge' all LAN ports into the bridge (albeit not in your example), but also as a base to attach your WLAN (AP-)interfaces to.
ipq40xx, as in the velop, switched between swconfig and the more modern DSA switch infrastructure post 22.03.x, so the procedures differ a lot, depending on the version. As DSA fixes a number of issues with the switch setup, I do recommend to migrate to a current master snapshot if more complex VLAN setups are desired.
The default configuration of OpenWrt on the vast majority of devices is as a router. It will have 2 interfaces -- wan (for the internet), and lan (for your internal/private network). The lan is associated with a bridge that connects the network to multiple physical interfaces (i.e. multiple ethernet ports and/or multiple radios (or 1 and 1). Without the bridge, you can only connect a network to a single physical interface.
If you want to create multiple independent subnets, there are several ways of approaching it (tagged VLANs, individually routed ports, or wifi only).
Please define the specifics of what you want to achieve, and also post your network configuration file so we can advise about how you would achieve your goals.

This tutorial you linked makes things much clear now. I was no aware of the DSA and while it is a little learning curve, it is sensible. I’ll work on my config now with this in mind.
