Day 1 - Frame Relay Multipoint Sub Interface - Inverse ARP & Static Mapping

Topik berlanjut ke Lab 3 masih dengan topology yang sama dengan Lab 1 dan Lab 2.

Dan masih dengan menggunakan software GNS3 sebagai emulator Cisco IOS.

Lab 3 - Frame Relay Multipoint Subinterface : Inverse-ARP 
 

R1 dan R2 adalah router yang akan dihubungkan dengan Frame Relay Switch (R3).

Dimana sebelumnya R3 sudah dikonfigurasi sebagai Frame Relay Switch sbb :

FRSW#show frame-relay route
Input Intf      Input Dlci      Output Intf     Output Dlci     Status
Serial0/0       102             Serial0/1       201             active
Serial0/1       201             Serial0/0       102             active

Konfigurasi pada R1:

R1(config)#default interface s0/0

R1(config)#int s0/0
R1(config-if)#encap frame-relay
R1(config-if)#
R1(config-if)#int s0
R1(config)#int s0/0.1 multipoint
R1(config-subif)#ip add 12.12.12.1 255.255.255.0
R1(config-subif)#frame-relay interface-dlci 102

Sedangkan konfigurasi pada R2 :

R2(config)#default interface s0/0

R2(config)#int s0/0
R2(config-if)#encap frame-relay
R2(config-if)#exit
R2(config)#int s0/0.1 multipoint
R2(config-subif)#ip add 12.12.12.2 255.255.255.0
R2(config-subif)#frame-relay interface-dlci 201

Verifikasi dari router R1 :

R1(config-fr-dlci)#do sh frame-relay map
Serial0/0.1 (up): ip 12.12.12.2 dlci 102(0x66,0x1860), dynamic,
              broadcast,, status defined, active
R1(config-fr-dlci)#exit
R1(config-subif)#do ping 12.12.12.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.12.12.2, timeout is 2 seconds:

Verifikasi dari R2 :

R2(config-fr-dlci)#do sh frame-relay map
Serial0/0.1 (up): ip 12.12.12.1 dlci 201(0xC9,0x3090), dynamic,
              broadcast,, status defined, active
R2(config-fr-dlci)#exit
R2(config-subif)#do ping 12.12.12.1

Bila dari R1 sudah bisa ping ke R2 maka konfigurasi sudah benar dan selesai.

Lab 4 - Frame Relay Multipoint Subinterface - Static Mapping.

Dengan topology yang sama dengan Lab 3, kita akan coba merubah menjadi static mapping pada frame relay multipoint.

Konfigurasi pada R1 :

R1(config)#int s0/0.1 multipoint
R1(config-subif)#no frame-relay interface-dlci 102
R1(config-subif)#frame-relay map ip 12.12.12.2 102 broadcast

Konfigurasi pada R2 :

R2(config)#int s0/0.1 multipoint
R2(config-subif)#no frame-relay interface-dlci 201
R2(config-subif)#frame-relay map ip 12.12.12.1 201 broadcast

Verifikasi pada router R1 :

R1(config-subif)#do sh frame-relay map
Serial0/0.1 (up): ip 12.12.12.2 dlci 102(0x66,0x1860), static,
              broadcast,
              CISCO, status defined, active
R1(config-subif)#do ping 12.12.12.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.12.12.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/18/68 ms

Verifikasi pada R2 :

R2(config-subif)#do sh frame-relay map
Serial0/0.1 (up): ip 12.12.12.1 dlci 201(0xC9,0x3090), static,
              broadcast,
              CISCO, status defined, active
R2(config-subif)#do ping 12.12.12.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.12.12.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/22/84 ms

Terlihat bahwa hasil verifikasi command show frame-relay map di R1 dan R2 berubah menjadi 'static, broadcast'.

Dan dari R1 sudah bisa ping ke R2, maka konfigurasi sudah benar dan selesai.
