Bridge

A Bridge operates at the physical network layer, connecting two or more
networks and forwarding packets between those networks. For example, a
Bridge will connect two or more physical Ethernet cable segments and
forward Ethernet packets from one segment to the other.

Bridges differ from routers in that bridges forward packets based on physical
addresses rather than on the IP Addresses that routers use to forward packets.
Bridges will not “blindly” forward packets from one network to others,
however. Rather, it learns all local physical addresses and forwards packets
based on those learned “tables.” This greatly reduces the number of
broadcasted packets, thus saving valuable bandwidth.

The Bridge Details screen shown in Figure 3.77 lets you access and configure
the parameters described below.
