  • 1. PRESESENTATION
    ON
    CONFIGURATION
    BRIDGES.
    Presented By:
    SWASTI ARYA
  • 2. WHAT ARE BRIDGES?
    • Internetworking device.
    • 3. Filters data traffic at a network boundary.
    • 4. Operates in both the physical and the data link layer of the OSI model.
    • 5. As a physical layer device, it regenerates the signal it receives. As a data link layer device, the bridge can check the physical addresses contained in the frame.
    • 6. Ethernet bridge, for example, inspects each incoming Ethernet frame.
  • WIRELESS ETHERNET BRIDGES
  • 7. TYPES OF BRIDGES
    • Transparent Bridge-
    • 8. The stations are completely unaware of the bridge’s existence.
    • 9. Reconfiguration of stations is unnecessary.
    • 10. Function are filtering frames, forwarding & blocking.
    • 11. Source Routing Bridge-
    • 12. Much of the bridging functions are performed by end systems, particularly the source.
    • 13. A sending station defines the bridges that the frame must visit.
    • 14. It was designed by IEEE to be used with token ring LANs.
  • CONFIGURATION OF BRIDGES
    • Network Bridge, is a feature of the Network Connections folder that allows a computer with multiple network adapters to act as a bridge, connecting different local area network (LAN) segments.
    • 15. Required to connect different networking technologies such as a wired Ethernet segment and a wireless segment.
    • 16. It is a new feature in Windows XP & there is no need to purchase an additional hardware-based bridge device.
    • 17. Requirement- network adapters installed for all the LAN segments.
  • A BRIDGE CONNECTING TWO LAN SEGMENTS
    (A & B)
  • 18. CONFIGURATION PROCEDURE
    My network plces|context menu “Bridge Connections”.
    WARNING
  • 19.
  • 20.
  • 21.
  • 22.
  • 23. All systems on the network are now accessible in “My Network Places”.
  • 24. DISABLING AND REMOVING THE BRIDGE
    • To disable the bridge, right-click its icon and choose Disable from the context menu.
    • 25. To remove a connection from the bridge, right-click the connection’s icon (not the bridge icon) and select Remove From Bridge.
  • ADVANTAGES
    • Self-configuring.
    • 26. Primitive bridges are often inexpensive.
    • 27. Reduce the size of collision domain by micro segmentation in non-switched networks.
    • 28. Transparent to protocols above the MAC layer.
    • 29. Allows the introduction of management/performance information and access control.
    • 30. LANs interconnected are separate, and physical constraints such as number of stations, repeaters and segment length don't apply.
    • 31. Helps minimize bandwidth usage.
    • 32. used to interconnect two LANs.
  • DISADVANTAGES
    • Does not limit the scope of broadcasts.
    • 33. Does not scale to extremely large networks.
    • 34. Buffering introduces store and forward delays; on average traffic destined for bridge will be related to the number of stations on the rest of the LAN.
    • 35. Bridging of different MAC protocols introduces errors.
    • 36. Because bridges do more than repeaters by viewing MAC addresses, the extra processing makes them slower than repeaters.
    • 37. Bridges are more expensive than repeaters.
  • DIFFERENCE BETWEEN BRIDGES & ROUTERS
    BRIDGES
    ROUTERS
    • Works at the DLL.
    • 38. Works with MAC (physical addresses).
    • 39. Provides a single path from one network segment to another.
    • 40. Works at the network layer.
    • 41. Works with IP (logical addresses).
    • 42. Routers are more sophisticated devices than bridges.
