LAB OSPF NETWORK NON BROADCAST
Bismillah….
Pada lab ini, kita akan mencoba mempelajari OSPF Network Non Broadcast, di lab yang ini kita juga akan kenalan dengan sebuah perangkat jaringan namanya Frame Relay Switch, apakah itu ? Nanti kita bahasnya yah, sekarang kita akan mempelajari metode – metode komunikasi, coba apa itu broadcast ?? Hmmm … BBM kali yah ? Bukan mas bro, BBM itu singkatan Blackbery Messanger memang sih di BBM juga terkenal dengan fitur untuk ngebroadcast message ke semua kontak, yah hampir mirip mirip lah hehhe. Kita bahas dikit yah yuk akhh..
Broadcast merupakan salah dari metode pengiriman IPv4, namun pada dasarnya metode pengiriman itu ada 3, yaitu Unicast. Multicast, dan Broadcast. Kita bahas satu satu yah.
1. Unicast, merupakan salah satu metode pengiriman IPv4 yang konsepnya “Point to Point” atau one to one, satu ke satu. Saya kasih analogi yah, ada 6 orang saling kenal sedang berkumpul, ada 2 orang yang sedang berbicara “hanya berdua saja” yaitu A dan B, tanpa 4 orang tersebut mendengarkan (C, D,E,F) ataupun ikut berbicara dengan 2 orang tersebut. Ketika si A berbicara maka yang mendengarkan hanya si B saja dan begitupun sebaliknya.
2. Multicast, merupakan salah satu metode pengiriman IPv4 yang memiliki konsep “One to Many”, atau bisa dibilang ngirim satu paket kepada banyak penerima. Saya kasih analogi yah, ada seorang pelatih sepak bola sedang melakukan pembicaraan kepada timnya, sedangkan timnya hanya mendengarkan ucapan pelatih, dan yang mendengarkan hanyalah “Timnya” bukan supporter maupun tim lawan tidak akan mendengarkan ucapan apalagi ikut dalam pembicaraan.
3. Broadcast, merupakan salah satu metode pengiriman IPv4 yang memiliki konsep “One to Every One” . Saya kasih analogi yah pada hari jumat seorang ustadz bertugas sebagai Khotib atau pemberi ceramah, ia berceramah kepada para jamaahnya, dan jamaahpun mendengarkan ceramah tersebut.
Nah… sampai disini paham yah, lanjut ke perangkat jaringan yaitu Frame relay Switch, apakah itu ? Okey perangkat Frame Relay ini, sebetulnyamah hampir sama dengan Switch yaitu tugas utamanya untuk menghubungkan device satu dengan device lainnya, namun cara kerjanya sangat berbeda, kalau switchkan ada dua jenis, switch biasa dan switch managable yang bisa di konfigurasi portnya seperti VLAN ( Virtual Lan), nah kalau Frame Relay, tugas utamnya sama dengan switch namun dengan cara kerja yang berbeda, di Frame Relay, ada beberapa teknologi yang berjalan di perangkat tersebut, contohnya DLCI (Data Link Connection), PVC (Permanent Virtual Circuit) MLI (Local Management Interface), nah teknologi DLCI ini berjalan di Layer 2, pokonya lumayan panjang kalau di bahas yah, yah pokoknya Switch dan Frame Relay terlihat hampir sama, namun nyatanya sangat berbeda jauh, saya juga gk bisa berkata kata yah, hehhe..
Untuk mempersingkat waktu, kita langsung ngelab yah, oh iya topologinya sama dengan yang diatas yah.
Step pertama konfigurasikan IP Adddres beserta IP Loopback di tip tiap Router.
di R1
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#int lo1
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int s2/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0
R1(config-if)#no shut
R1(config-if)#
di R2
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#int lo1
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int s2/0
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#no shut
R2(config-if)#
di R3
R3#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R3(config)#int lo1
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#int s2/0
R3(config-if)#ip add 12.12.12.3 255.255.255.0
R3(config-if)#no shut
R3(config-if)#
Step ke dua yaitu konfigurasi Frame Relaynya yah.
Di Double klik aja perangkatnya nanti dan create seperti gambar berikut:
Step ketiga, konfigurasi frame relay di tiap port yang terhubung ke frame relay.
Di R1
R1(config)#int s2/0
R1(config-if)#encap
R1(config-if)#encapsulation fr
R1(config-if)#encapsulation frame-relay
R1(config-if)#frame-relay map ip 12.12.12.2 102 broadcast
R1(config-if)#frame-relay map ip 12.12.12.3 103 broadcast
R1(config-if)#exit
R1(config)#do wr
Building configuration...
[OK]
Di R2
R2(config)#int s2/0
R2(config-if)#encapsulation frame-relay
R2(config-if)#frame-relay map ip 12.12.12.1 201 bro
R2(config-if)#frame-relay map ip 12.12.12.3 201
R2(config-if)#exit
R2(config)#
R2(config)#do wr
Building configuration...
[OK]
Di R3
R3(config)#int s2/0
R3(config-if)#encapsulation frame-relay
R3(config-if)#frame-relay map ip 12.12.12.1 301 bro
R3(config-if)#frame-relay map ip 12.12.12.2 301
R3(config-if)#exit
R3(config)#exit
R3(config)#do wr
Building configuration...
[OK]
Selanjutnya konfigurasikan Frame Relay di Router ABR, nah di lab ini Router 2 adalah ABR,
R2(config)#int s2/0
R2(config-if)#encapsulation frame-relay
R2(config-if)#frame-relay map ip 12.12.12.1 201 bro
R2(config-if)#frame-relay map ip 12.12.12.3 201
R2(config-if)#exit
R2(config
Kemudian step selanjutnya yaitu konfigurasikan routing OSPF di semua router dengan area 0.
R1(config)#router ospf 1
R1(config-router)#network 1.1.1.1 0.0.0.0 area 0
R1(config-router)#network 12.12.12.1 0.0.0.255 area 0
R1(config-router)#exit
R1(config)#do wr
Building configuration...
[OK]
R1(config)#router ospf 1
R1(config-router)#router-id 1.1.1.1
R1(config-router)#exit
R1(config)#do wr
Building configuration...
[OK]
di R2
R2(config-if)#
R2(config-if)#exit
R2(config)#router ospf 2
R2(config-router)#router-id 2.2.2.2
R2(config-router)#network 2.2.2.2 0.0.0.0 area 0
R2(config-router)#network 12.12.12.2 0.0.0.255 area 0
R2(config-router)#exit
R2(config)#do wr
Building configuration...
[OK]
di R3
R3(config)#router ospf 3
R3(config-router)#router-id 3.3.3.3
R3(config-router)#network 3.3.3.3 0.0.0.0 area 0
R3(config-router)#network 12.12.12.3 0.0.0.255 area 0
R3(config-router)#exit
R3(config)#do wr
Building configuration...
[OK]
Kemudian cek routing tabel di R3
R3(config)#do sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
a - application route
+ - replicated route, % - next hop override
Gateway of last resort is not set
3.0.0.0/32 is subnetted, 1 subnets
C 3.3.3.3 is directly connected, Loopback1
R3(config)#
di routing tabel tersebut tidak adanya informasi router tetangga, artinya routing OSPF tidak bisa terbentuk, nah agar bisa saling terhubung, R1 R2 dan R3 harus saling memperkenalkan diri, artinya kita harus konfigurasi karena berhubung target / goalnya lab ini Non Broadcast artinya R2 dan R3 harus diperkenalkan secara manual ke R1 yang bertindak sebagai DR atau Design Router
Di R1
R1(config)#router ospf 1
R1(config-router)#neighbor 12.12.12.2
R1(config-router)#neighbor 12.12.12.3
R1(config-router)#exit
Di R2
R2(config)#int s2/0
R2(config-if)#ip ospf priority 0
R2(config-if)#exit
R2(config)#do wr
Building configuration...
[OK]
Di R3
R3(config)#int s2/0
R3(config-if)#ip ospf priority 0
R3(config-if)#exit
R3(config)#do wr
Building configuration...
[OK]
selanjutnya matikan semua interface di R1, R2 dan R3 trus nyalakan lagi
semuanya
udah gitu tunggu sampai adjecency semua router, kemudian cek OSPF Neighbor
cek neighbor di R1
R1#sh ip ospf nei
Neighbor ID Pri State Dead Time Address Interface

LAB OSPF NETWORK BROADCAST
Bismillah..
Pada lab kali ini, kita akan mencoba untuk merubah network type pada lab sebelumnya yaitu OSPF Network Type Non Broadcast, di rubah menjadi OSPF Network Type Broadcast, untuk topologinya sama komplit dengan ip address serta ip loopbacknya, biar lebih paham kita langsung konfigurasi yah, yuk akh…
Matikan neighbor R2 dan R3 di routingan ospf R1 / ABR

terbentuk LSAnya , sampai sini selesei yah.
Salam Ngoprek
LAB OSPF NETWORK POINT TO POINT
Bismillah..
Pada kesempatan ini, kita akan mencoba mempelajari OSPF Network Point to Point, sebelum kita konfiurasi ada baiknya kita tengok gambar topologi di atas, pada topologi tersebut ada yang namnya
Sub Interface, apa itu ? Okey saya jelasin yah, Sub Interface adalah sebuah metode untuk pengalamatan beberapa IP Address dalam 1 Interface saja, jadi 1 Interface Ethernet bisa di berikan beberapa IP address, nah gunanya yaitu untuk komunikasi point to point dengan router DR (Design Router) di Network OSPF.
Sekarang kita coba konfigurasi yah, yuk akh…
Step pertama konfigurasi IP Address di Sub Interface dan IP Loopback di semua router, kemudian konfigurasi point to point di masing masing interface yang terhubng ke frame relay.
di R1
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#int lo1
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-subif)#int s2/0
R1(config-if)#encapsulation frame-relay
R1(config)#int s2/0.12 point-to-point
R1(config-subif)#ip add 12.12.12.1 255.255.255.0
R1(config-subif)#frame-relay interface-dlci 101
R1(config-fr-dlci)#exit
R1(config)#int s2/0.13 point-to-point
R1(config-subif)#ip add 13.13.13.1 255.255.255.0
R1(config-subif)#frame-relay interface-dlci 102
R1(config-fr-dlci)#exit
Nyalakan interface s2/0 dan s2/0.13 dan s2/0.12
R1(config)#int s2/0
R1(config-if)#no shut
R1(config-if)#int s2/0.12 point-to-point
R1(config-subif)#no shut
R1(config-if)#int s2/0.13 point-to-point
R1(config-subif)#no shut
kemudian di R2
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#int lo1
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-subif)#int s2/0
R2(config-if)#encapsulation frame-relay
R2(config)#int s2/0.12 point-to-point
R2(config-subif)#ip add 12.12.12.2 255.255.255.0
R2(config-subif)#frame-relay interface-dlci 201
Nyalakan interface s2/0 dan s2/0.12
R2(config)#int s2/0
R2(config-if)#no shut
R2(config-if)#int s2/0.12 point-to-point
R2(config-subif)#no shut
di R3
R3(config)#int lo1
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#int s2/0
R3(config-if)#encapsulation frame-relay
R3(config)#int s2/0.13 point-to-point
R3(config-subif)#ip add 13.13.13.2 255.255.255.0
R3(config-subif)#frame-relay interface-dlci 301
R3(config-fr-dlci)#exit
Nyalakan interface s2/0 dan s2/0.13
R3(config)#
R3(config)#int s2/0
R3(config-if)#no shut
R3(config-if)#int s2/0.13 point-to-point
R3(config-subif)#no shut
Kemudian kita cek di masing masing interface apakah interface network type nya sudah berubah menjadi point to point.
Cek OSPF Interface di setiap router
di Router 1

LAB OSPF NETWORK POINT TO MULTI POINT
Bismillah…..
Pada lab ini, kita akan mencoba belajar OSPF Point to Multi Point, maksudnya pengiriman dari satu titik ke berbagai titik., biar mudah dimengerti kita konfigurasi saja yah.
Step pertama konfigurasikan IP Address, IP Loopback dan Routingan OSPFnya di masing masing router sesuai gambar toplogi diatas.
Di R1
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#int lo1
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int s2/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0
R1(config-if)#no shut
R1(config-if)#
Di R2
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#int lo1
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int s2/0
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#exit
Di R3
R3#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R3(config)#int lo1
R3(config-if)#ip add
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#int s2/0
R3(config-if)#ip add 12.12.12.3 255.255.255.0
R3(config-if)#no shut
R3(config-if)#exit
Setting perangkat Frame Relaynya yah sesuaikan seperti di gambar topologi diatas, kemudian konfigurasi frame relay di setiap interface router yang terhubung ke Frame relay.
Di Router 1
R1(config)#int s2/0
R1(config-if)#encapsulation frame-relay
R1(config-if)#frame-relay map ip 12.12.12.2 101 broad
R1(config-if)#frame-relay map ip 12.12.12.3 102 broad
R1(config-if)#exit
Di Router 2
R2(config)#int s2/0
R2(config-if)#encapsulation frame-relay
R2(config-if)#frame-relay map ip 12.12.12.1 201 bro
R2(config-if)#frame-relay map ip 12.12.12.3 201
R2(config-if)#exit
R2(config)#exit
Di Router 3
R3(config)#int s2/0
R3(config-if)#encapsulation frame-relay
R3(config-if)#frame-relay map ip 12.12.12.1 301 bro
R3(config-if)# frame-relay map ip 12.12.12.2 301
R3(config-if)#exit
Setelah dimappingkan, langsung masukin networknya ke OSPF dan deklarasikan
interface yang mengarah ke framerelay menjadi network type : point-to-multipoint
R1(config)#router ospf 1
R1(config-router)#router-id 1.1.1.1
R1(config-router)#network 1.1.1.1 0.0.0.0 area 0
R1(config-router)#network 12.12.12.1 0.0.0.255 area 0
R1(config-router)#exit
R1(config)#int s2/0
R1(config-if)#ip ospf network point-to-multipoint
R1(config-if)#exit
R1(config)#exit
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#router ospf 1
R2(config-router)#router-id 2.2.2.2
R2(config-router)#network 2.2.2.2 0.0.0.0 area 0
R2(config-router)#network 12.12.12.2 0.0.0.255 area 0
R2(config-router)#exit
R2(config)#int s2/0
R2(config-if)#ip ospf network point-to-multipoint
R2(config-if)#
R3(config)#router ospf 1
R3(config-router)#router-id 3.3.3.3
R3(config-router)#network 3.3.3.3 0.0.0.0 area 0
R3(config-router)#network 12.12.12.3 0.0.0.255 area 0
R3(config-router)#exit
R3(config)#int s2/0
R3(config-if)#ip ospf network point-to-multipoint
R3(config-if)#
cek keseluruhan R1 inteface yang mengarah ke frame relay

LAB OSPF NETWORK POINT TO MULTI POINT NON BROADCAST
Bismillah…
Pada lab kali ini, kita akan mengkonfigurasi OSPF Point to Multi Point Non Broadcast, untuk topologinya masih sama dengan lab yang sebelunya yah, plus konfigurasinya juga sama, hanya perubahan type network saja kok, kita mulai yah labnya oke oke..
Non aktifkan network type point to multipoint di ganti dengan point to multi point broadcast di setiap interface R1 R2 dan R3 yang terhubung ke frame relay.
di R1
R1(config)#int s2/0
R1(config-if)#ip ospf network point-to-multipoint non-broadcast
di R2
R2(config)#int s2/0
R2(config-if)#ip ospf network point-to-multipoint non-broadcast
R2(config-if)#
di R3
R3#conf t
R3(config)#int s2/0
R3(config-if)#ip ospf network point-to-multipoint non-broadcast
Kemudian tambahkan neigbor R2 dan R3 di Router 1 yang bertindak sebagai ABR
R1(config)#router ospf 1
R1(config-router)#neighbor 12.12.12.2
R1(config-router)#neighbor 12.12.12.3
R1(config-router)#exit
Tunggu sampai adjencency antar router
setelah selesei coba cek routing tabel
R1#sh ip route
