CISCO ROUTER WITH A FRAME RELAY SWITCH EXAMPLE:
The Frame-Relay Intf-Type DCE Command Specifies The Interface To Handle LMI Like A Frame Relay DCE Device. This Command Also Enables FRSW To Function As A Switch Connected To A Router. And The Clock Rate Is Necessary On The DCE End Of The Connection So We Have To Put It Here (But In Fact Not All IOS Versions Require This, You Can Check Or Verify The DCE And Clock Rate With The Show Controller Serial X/Y Command).
The Frame-Relay Route 403 Interface Serial 0/1 304 Command Means Frame-Relay Traffic Comes To FR Switch Which Has A DLCI Of 403 Will Be Sent To Interface Serial0/1 With A DLCI Of 304.
Also Please Notice That There Is No IP Address Configured On The Frame Relay Switch. We Can Verify The Configuration Of The FRSW With Show Frame-Relay Route Command.
Note: The Output Above Is Taken After All Routers Have Been Configured So If You Do This Command In Your Lab At This Moment The Status Would Be Inactive Because You Have Not Turned On The Serial Interfaces On R1, R2, R3, R4.
The Frame-Relay Map Command Performs Static Addressing Mapping And It Disables Inverse ARP On The Specified DLCI. This Command Is Supported On The Physical Interface And It Should Be Used When The Far End Frame Relay Device Does Not Support Inverse ARP. If We Choose To Disable Inverse ARP, We Must Perform A Static Mapping Of L2 To L3, As Well As Associate The DLCI To The Interface.
Note:Configuring Static Map Statements (Like Frame-Relay Map IP Command) Automatically Disables Inverse ARP. Physical Interfaces Have Inverse ARP Enabled By Default.
FRAME-RELAY INTERFACE-DLCI:
We Notice That In This Command Only The DLCI Is Specified And This Command Just Associates The DLCI With The Subinterface.
This Is Because Point-To-Point Network Only Connects With One Remote Destination. Therefore This Command Is Mostly Used Under Point-To-Point Subinterface (But It Can Be Still Used On Physical Interface Although It Has No Effect Because All Unassigned DLCIs Belong To That Physical Interface By Default).
On Point-To-Point Subinterface, Inverse ARP Requests Are Not Sent Out Regardless If It Is Enabled On The Physical Interface Or Not. It Is Also Not Required To Enable Or Disable Inverse ARP, Because There Is Only A Single Remote Destination On A PVC And Discovery Is Not Necessary. Also Notice That The Frame-Relay Map Command Is Not Allowed On A Point-To-Point Subinterface.
Note: Using Subinterface Can Avoid The Split-Horizon Problem.
WE CAN CHECK WHICH TYPE OF MAPPING WAS CONFIGURED WITH THE COMMAND “Show Frame-Relay Map”:
Dynamic Means The Mapping Was Done Using Inverse ARP.
Static Means The Mapping Was Done Manually.
THE FIRST STEP IN CONFIGURING A CISCO ROUTER TO ACT LIKE A FRAME RELAY SWITCH IS TO ENABLE FRAME RELAY SWITCHING:
CONFIGURE FRAME RELAY SWITCH:
We Should Change The Name Of Routre 5To FR (Frame Relay Switch).
Router5(Config)#Hostname FR - > The Very First Command To Turn On The Frame Relay Switching Feature On FR
FR(config)#Frame-Relay Switching
ONCE ENABLED, YOU THEN CONFIGURE THE SERIAL INTERFACES CONNECTED TO THE OTHER ROUTERS.

CONCLUSION:
The Goal Of This Article Is To Give An Easy Way To Understand The “CCNP TSHOOT Example References" And Also We Hope This Guide Will Help Every Beginner Who Are Going To Start Cisco Lab Practice Without Any Doubts. Some Topics That You Might Want To Pursue On Your Own That We Did Not Cover In This Article Are Listed Here!Hands - On Experience Is An Invaluable Part Of Preparing For The Lab Exam And Never Pass Up An Opportunity To Configure Or Troubleshoot A Router ( If You Have Access To Lab Facilities, Take Full Advantage Of Them) There Is No Replacement For The Experience You Can Gain From Working In A Lab, Where You Can Configure Whatever You Want To Configure And Introduce Whatever Problems You Want To Introduce, Without Risk Of Disrupting A Production Network. Thank You And Best Of Luck
