Is it possible to mix router and switch mode in same network?

[Noah Overcash]

What I did for my Big Sur install on tinc, not sure it’s recommended or a good idea though, is to run openvpn on one of the nodes in my network which bridged into tinc. Therefore, I could use all the routing features of tinc through that node over plain IPSEC or PPPoE which macOS (and many mobile/other devices) handle much better.

Those VM’s on the physical nodes are connected via a 2nd interface to an openvswitch bridge on which those physical nodes provide the connection outside. As extra thing, all tinc nodes are in the same /24.

And if not what changes would I need to make to keep the current setup with the bridges on the physical nodes in tact? Or almost intact?
