 Bridge
 ######
 
-A Bridge is a way to connect two Ethernet segments together in a protocol
-independent way. Packets are forwarded based on Ethernet address, rather than
-IP address (like a router). Since forwarding is done at Layer 2, all protocols
-can go transparently through a bridge. The Linux bridge code implements a
-subset of the ANSI/IEEE 802.1d standard.
