I have a customer who's Eero seems to be exposing either their entire LAN L2 or at least several Eero MACs to the SP side consistently upon every reboot, and given the lack of configurability that the Eero presents, I'm at a loss to figure out how to make it not do that.
I doubt you're going to be able to make it not do that, and I suspect a very large number of consumer routers do this. At heart, they are typically based around an SoC and a switching module; until it boots enough to configure the switching module, it is a dumb switch, and will act like one. If the access technology you're using supports it, some form of mac locking/filtering your access customers is the usual way SPs handle unwanted traffic. --msa
