Each interface of a router is a separate broadcast domain. -The term Bridging appears before routers and hubs, so it is common to hear people refer to a bridge as a switch and vice versa. Bridges and switches do essentially the same thing - separate conflicting domains within a LAN (the reality now is that physical bridges can no longer be purchased, only LAN switches; but LAN switches use bridging technology, so Cisco still refers to them as multi-interface bridges).Which means that the switches basically just have some intelligent multi-interface bridges, right? It's basically the same, but still a little different. The switch does offer bridging capabilities, but it also offers enhanced management capabilities and features on top of that. Also, bridges typically offer 2 or 4 interfaces, while switches can offer 16, not to mention some crossovers can offer hundreds!Using a bridge in a network reduces the likelihood of conflicts in broadcast domains and increases the number of conflicting domains in the network. More bandwidth can be made available to users by doing this. And remember that using hubs in an Ethernet network helps reduce congestion. In short, design the network carefully!All of these network interconnect devices are integrated in the network shown in Figure 2.3. Keep in mind that the router doesn't just provide the bandwidth for eachLAN interface to separate broadcast domains, but also to separate conflict domains.Did you notice from Figure 2.3 that the router is in the center of the network and connects each physical network together? This deployment structure must be used in this example because older technology-bridges and hubs-is used here.The interconnected network at the top of Figure 2.3 uses a bridge, which connects the hubs and routers together. The bridge separates the conflicting domains, but hosts connected to the same hub still belong to the same broadcast domain. Also, the bridge creates only two conflict domains, so devices connected under the same hub all belong to the same conflict domain. This feature is chickenshit, but it is still better than having all hosts in the same conflict domain.Note also: the 3 hubs below the diagram are connected to each other and to the router, which creates a conflict domain and a broadcast domain. This really makes this bridged network look a lot better!Although bridges/switches are used to segment the network, they do not isolate broadcast or multicast packets!
