Router# show frame-relay map SerialO (up): ip 192.168.2.2 dlci 32(0x20, 0xlC80)z static, Broadcast, CISCO, status defined, deletedIn this example, note that the DLCI is manually mapped (static), with a status of deleted.To view the manual or reverse ARP mapping of the Layer 3 address to the DLCI, use the command show frame-relay mapo For VCs that are dynamically learned via reverse ARP, the output of this command contains the keyword dynamic. when statically mapping a Layer 3 address to a DLCI, if the status of the VC is deleted, it is probably because you have configured a Frame Relay switch with a DLCI number that does not exist in the switch. Use this command to view the LMI type, the local DLCI number, the remote Layer 3 address, and the status of the VC. Video 25.08A multimedia demonstration of using the command show frame-relay map on a router is included in the companion digital resource to this book.Hands-On Exercises 25.1Configuring Frame Relay The previous sections discussed how to configure Frame Relay on a physical serial interface; in this exercise, you will configure a simple Frame Relay connection to deepen your understanding of these elements. Reverse ARP is used here to resolve the VC address; the DLCI number at both ends is 100o You will use the BosonNetSim simulator for this experiment; see the Preface section of this book for a diagram of the network used by this simulator. To start this simulator, click the tab Labs in the lower left corner of the window,then click the tab McGraw-Hill in the upper left corner (tab Standard and Custom to the right). Next, double-click Exercise25-1, which will load the experimental configuration based on the exercises in Chapters 10 and 15. 1. Disable interface serialO (which is a dedicated point-to-point connection) on router 2600-1 so that you can configure Frame Relay. Click the Lab Instructions tab and select 2600-1 from the drop-down list Devices; you can also click the NetMap tab and double-click the device icon 2600-U to execute the following commands: configure terminal, interface serialO, shutdown, and end. use the command show interfaces to check the status of the interfaces; currently, only interface faO/O is enabled on Router 2600-1 _h. 2. Disable interface serialO (which is a dedicated point-to-point connection) on router 2600-2 so that Frame Relay can be configured. Click the tab Lab Instructions and select 2600-2 from the drop-down list Devices; you can also click the tab NetMap, then double-click the device icon 2600-2o execute the following command: configure terminalinterface serialO^shutdown and end. use the command show interfaces to check the status of the interface; currently, only interface faO/O is enabled on router 2600-2Ji.3. on routerEnable Frame Relay on the 2600-1: enable interface serial1; set the Frame Relay frame type to Cisco; set the LMI type to ITU.T; assign the IP address. Click the label Lab Instructions and select 2600-1 from the drop-down list Devices; also click the label NetMap, then double-click the device icon 2600-1o Enable the Frame Relay interface: configure terminaR interface seriall and no shutdowno Set the encapsulation type and frame type: encapsulation frame-relayo set LMI type: frame-relay Imi-type q933a. assign IP address to the interface: ip address 192.168.10.1 255.255.255.0. exit configuration mode: end.4. Check the interface and4. Check the operational status of the interface and LMI. Use the command show interfaces to verify that the status of the interface is knocking and up, and that the LMI is operating normally. Use the command show frame-relay Imi to confirm that the router is sending and receiving LMI information.
