I'd have thought that hardwired hubs are long gone, that all devices
with multiple Ethernet ports are switches and therefore software-based.
Indeed, many routers can be configured as VLANs.

I had a different problem recently, trying to work out which of a few
high-bandwidth 802.11ac routers could be configured in pairs as wireless
point-to-point links, which also uses the term 'bridging', and no, they
can't all do it. But documentation is usually very poor for the
lesser-used functions of most things. 'Bridging' is also used to mean
wireless repeating, which is a different thing again.

The network between the routers is a low-security DMZ, with access to
the main network only through the port-forwarding of the second router.

I have an Internet router, which provides occasional wireless for
visitors, and a server acting as a firewall leading to the rest of the
network, so there's no wireless access to the main network, though I do
have an old wireless router that I can plug in if I need it temporarily.
