Your work for a large ISP that still has some old frame-relay equipment. One of your customers wants their sites to be directly connected. Since you know frame relay pretty wel you know you can setup some bridging.


  • All IP addresses have been preconfigured for you.
  • Enable frame relay encapsulation on the serial0/0 interfaces of router Compact and Decrease.
  • Configure a bridge group on router Compact and Decrease, use IEEE. Apply the bridge group to the serial0/0 interfaces.
  • Ensure router Jack and Emma can ping each other and that they have multicast and broadcast capabilities.
