Chapter 2 Bridging About bridging methods; viewing and managing bridging interfaces; using the Bridge Status window; viewing bridge statistics; using Spanning Tree; using the Filtering Database; configuring duplex modes; using the Interface Configuration window; and setting Bridge Translation Bridging Basics Bridges are used in local area networks to connect two or more network segments and to control the ßow of packets between the segments. Ideally, bridges forward packets to another networkStreszczenie treści zawartej na stronie nr. 20
Bridging Þlters a packet if it determines that the packetÕs destination address exists on the same side of the bridge as the source address. If two or more bridges are connected to the same Ethernet LAN segmentÑplaced in parallelÑonly a single bridge must be allowed to forward data frames onto that segment. If two or more bridges were forwarding data frames onto the same Ethernet segment, the network would soon be ßooded.
