And there-in lies the problem. Routers and Bridges are protocol level dependent and thus will not accept anything they are not set up to pass. TCP/IP routers that don't support AppleTalk will reject signals that are not routable, and may even just throw a panic fit (are these cheap routers or expensive ones?) Switches and Hubs however are packet level dependent and thus pass any packet that is designated to pass packets from one MAC address to another, regardless of what it contains.
Actually Hubs (originally known as repeaters) simply pass bits around and don't terribly much care if they are even Ethernet (oversimplification). Switches actually receive, hold and resend Ethernet packets but don't care about what is in them (if they do then they are kind of moving out of the definition of "Switch"). The problem often comes in the way marketing types tend to use "hub" for "switch" or the term "switching Hub". Also so called dual speed hubs muck it up more.
