Command Line

Command Description
encapsulation Frame-relay Enables Frame-relay encapsulation on an interface
Frame-relay interface-dlci dlci Assigns a DLCI to an interface or subinterface
Interface interface.subinterface point-topoint Creates a frame-relay point-to-point subinterface
Show frame-relay lmi Display LMI statistics
Show frame-relay pvc Displays PVC characteristics
Show frame-relay map Displays the mapping between the local DLCI and the next hop IP address.

Task 1: Setting up a Basic Frame-relay Link.

Step 1: Access the CLI on the router.

Step 2: Disable the serial interface

Step 3: Remove the current IP address

R(config-if)#no IP address

Step 4: Change the encapsulation to Frame-relay

Task 2: Supporting Frame-relay using Subinterfaces

In this task the two routers will take on different frame-relay roles, R1 will act as the Framerelay DCE and R2 will become a Frame-relay DTE

Step 1: R1 only….

The following commands will setup Frame-relay switching, Frame-relay DCE and a framerelay point-to-point subinterface on router R1.

R1(config)#frame-relay switching
R1(config)#interface s0/0.111 point-to-point
R1(config-subif)#ip address 172.17.1.1 255.255.255.252
R1(config-subif)#frame-relay interface-dlci 111
R1(config-fr-dlci)#end
R1#conf t
R1(config)#interface s0/0
R1(config-if)#frame-relay intf-type dce
R1(config-if)#no shut

Step 1: R2 only…. Acting as a Frame-relay DTE client.

R2(config)#interface s0/0.111 point-to-point
R2(config-subif)#ip address 172.17.1.2 255.255.255.252
R2(config-subif)#frame-relay interface-dlci 111
R2(config-fr-dlci)#end
R2#conf t
R2(config)#interface s0/0
R2(config-if)#no shut

Step 2: Execute the sh frame-relay pvc command.
Below are example snapshots.

What are the 3 possible states of a PVC?

When are frame marked DE?

Step 3: Ping the IP address of the Peer device, this should be successful!
