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
