Any device that operates at a network layer higher than the one used by bridges (i.e., the link layer or L2) is considered a host in the context of this and the following bridging chapters (routers included). A host (i.e., a Linux system) can, if configured appropriately, be both a bridge and a host that a user can use as a standard workstation.

Therefore, the PCs in all the figures do not run any bridging code unless stated otherwise in the text.
