DLCI stand for?
show frame-relay pvc
show frame-relay route]
show ip route
show ip route

4. Verify the configuration
4.1 ping from R1 to R2 and from R2 to R1
4.2 Get PVC information
R1#show frame-relay pvc
R2#show frame-rely pvc
FR Switch#show frame-relay pvc
4.3 Verify Frame Relay mappings
R1# show frame-relay map
R2# show frame-relay map
FR switch: none
4.4 Debug the Frame Relay LMI
R1# debug frame-relay lmi

5. Troubleshooting Frame Relay
5.1 Remove the frame-relay map from R1
R1# configure terminal
R1(config)# interface serial 0/0/1
R1(config-if)# encapsulation frame-relay
R1(config-if)# no frame-relay map ip 10.1.1.2 102 broadcast

5.2 ping R1 dari R2 (Ping ke yang tidak ada frame-relay map ip nya)
R2# ping 10.1.1.1
Ping should be failed

5.3 Issue the debug ip icmp command on R1(Router yang tidak ada frame-relay map ip nya)
R1# debug ip icmp

5.4 Ping R1 dari R2
R2# ping 10.1.1.1

5.5
As is shown by this debug message, the ICMP packet from R2 is reaching R1.

5.6 Issuing the show frame-relay map command
R1# show frame-relay map

6. Change the Frame Relay encapsulation type
6.1 Change the frame relay encapsulation on serial0/0/1 on R2 to IETF (Notice: interface that goes to router R1)
R2(config-if)# encapsulation frame-relay ietf
Notice:
1. no EIGRP break-up
2. FR Switch dan R2 still passing traffic

6.1 Change the encapsulation type back to the default:
R2(config-if)# encapsulation frame-relay

7. Change the LMI type
7.1 On R2
R2# configure terminal
R2(config)# interface serial 0/0/1
R2(config-if)# encapsulation frame-relay
R2(config-if)# frame-relay lmi-type ansi
R2(config-if)# ^Z
R2# copy run start

7.2 Show interface on R2
Serial0/0/1 is up, line protocol is down

7.3 Show frame-relay lmi on R2
R2# show frame-relay lmi

7.4 Issue debug frame-relay lmi command on R2. Notice that LMI packets are no longer showing up in pairs.
R2# debug frame-relay lmi

7.5 Leave debugging on and restore the LMI type to Cisco on R2
R2(config-if)# frame-relay lmi-type cisco


8. Configure frame-relay and subinterfaces
a. point-to-point sub interfaces
b. point-to-multipoint subinterfaces. Point-to-point

8.1 On FR switch, create a new PVC between R1 and R2
FR-Switch(config)# interface serial 0/0
FR-Switch(config-if)# frame-relay route 112 interface serial 0/0/1 212
FR-Switch(config-if)# interface serial0/0/1
FR-Switch(config-if)# frame-relay route 212 interface serial0/0/0 112

8.2 Create and configure a point-to-point subinterface on R1
Create subinterface 112 as a point-to-point interface. Frame Relay encapsulation must be specified on the physical interface before subinterface can be created:
R1(config)# interface serial 0/0/1.112 point-to-point
R1(config-if)# ip address 10.1.1.5 255.255.255.252
R1(config-if)# frame-relay interface-dlci 112

8.3 Create and configure a point-to-point sub-interface on R2
R2(config)# interface serial 0/0/1.212 point-to-point
R2(config-if)# ip address 10.1.1.6 255.255.255.252
R2(config-subif)# frame-relay interface-dlci 212

8.4 Verify connectivity
8.4.1 Ping R2 dari R1
R1# ping 10.1.1.6
R2# ping 10.1.1.5

R1# show frame-relay pvc
R2# show frame-relay pvc
FR-Switch# show frame-relay pvc

R1# show frame-relay map
R2# show frame-relay map
FR-Switch# show frame-relay route

8.5 Debug the frame-relay LMI
