Frame relay ospf point-to-multipoint non-broadcast

Konfigurasi IP & encapsulasi, no invers-arp di R1:

R1(config)#int s0/0

R1(config-if)#ip add 123.123.123.1 255.255.255.0

R1(config-if)#no sh

R1(config-if)#encapsulation frame-relay

R1(config-if)#no frame-relay inverse-arp

R1(config)#int l0

R1(config-if)#ip add 1.1.1.1 255.255.255.255

Konfigurasi IP & encapsulasi, no invers-arp di R2:

R2(config)#int s0/0

R2(config-if)#ip add 123.123.123.2 255.255.255.0

R2(config-if)#encapsulation frame-relay

R2(config-if)#no frame-relay inverse-arp

R2(config)#int l0

R2(config-if)#ip add 2.2.2.2 255.255.255.255

Konfigurasi IP & encapsulasi, no invers-arp di R3:

R3(config)#int s0/0

R3(config-if)#ip add 123.123.123.3 255.255.255.0

R3(config-if)#encapsulation frame-relay

R3(config-if)#no frame-relay inverse-arp

R3(config-if)#ip add 3.3.3.3 255.255.255.255

mapping ip ke frame-relay di setiap interface tanpa menambahkan perintah "broadcast" :

R1(config-if)#int s0/0

R1(config-if)#frame-relay map ip 123.123.123.2 102

R1(config-if)#frame-relay map ip 123.123.123.3 103

R2(config-if)#int s0/0

R2(config-if)#frame-relay map ip 123.123.123.1 201

R2(config-if)#frame-relay map ip 123.123.123.3 201

R3(config-if)#int s0/0

R3(config-if)#frame-relay map ip 123.123.123.1 301

R3(config-if)#frame-relay map ip 123.123.123.2 301

check frame-relay map nya :

R1#sh frame-relay map

Serial0/0 (up): ip 123.123.123.2 dlci 102(0x66,0x1860), static,

              CISCO, status defined, active

Serial0/0 (up): ip 123.123.123.3 dlci 103(0x67,0x1870), static,

              CISCO, status defined, active

Konfigurasi OSPF frame-relay point-to-multipoint non-broadcast

R1-R3(config)#int s0/0

R1-R3(config-if)#ip ospf network point-to-multipoint non-broadcast

Konfigurasi OSPF di semua router :

R1-R3(config)#router ospf 1

R1-R3(config-router)#network 0.0.0.0 255.255.255.255 area 0

ketika kita konfigurasi OSPF, semua router tidak mau bertukar-menukar routing update, karena kita membuat tipe jaringannya adalah point-to-multipoint non-broadcast, artinya disitu tidak dapat melewatkan paket multicast. maka kita harus mendefinisikan neighbour dari OSPF secara manual , karena R1 sebagai hub, jadi di router itulah yang hanya di konfigurasi neighbour :

R1(config)#router ospf 1

R1(config-router)#neighbor 123.123.123.2

R1(config-router)#neighbor 123.123.123.3

verifikasi :

test ping ke semua router, harusnya dah bisa
