You first need to configure FR Switch as a Frame Relay switch and create DLCIs.

Page 4 of 24 CCNA Exploration Accessing the WAN Frame Relay Lab Basic Frame Relay Step 1 Configure FR Switch as a Frame Relay switch and create a PVC between R1 and R2. This command enables Frame Relay switching globally on the router allowing it to forward frames based on the incoming DLCI rather than on an IP address basis FR-Switch config frame-relay switching Change the interface encapsulation type to Frame Relay. Like HDLC or PPP Frame Relay is a data link layer protocol that specifies the framing of Layer 2 traffic. FR-Switch config interface serial 0 0 0 FR-Switch config clock rate 64000 FR-Switch config-if encapsulation frame-relay Changing the interface type to DCE tells the router to send LMI keepalives and allows Frame Relay route statements to be applied. You cannot set up PVCs using the frame-relay route command between two Frame Relay DTE interfaces. .
