Tujuan Praktikum
1.       Mahasiswa dapat mengetahui bagaimana caranya Verify RIP routing using show and debug commands
2.        Mahasiswa melakukan Observe automatic summarization at boundary router and Gather information about RIP processing using the debug ip rip command.
Pendahuluan
Karakteristik RIPv1:
- merupakan distance vector routing protocol
- classful routing protocol
- max hop count:15. 16 -> unreachable
- periodic update: 30s
- update dikirim secara broadcast(255.255.255.255)
- mendukung equal cost load balancing. Secara default adalah 4 path, sedang max path: 6
- menjalankan auto-summary secara default
- paket yang dikirim berjenis UDP dengan nomor port 520
- bisa mengirimkan paket update RIPv1 dan menerima paket update RIPv1 & v2
- AD: 120

 
Pada saat instalasi, router-router yang menjalankan RIP akan membroadcast paket request kepada router lain yang isinya adalah meminta network-network yang dimiliki router lain. Router lain yang menerima paket request akan mengirimkan respon. Setelah itu mereka baru bertukar-tukaran info network yang dimiliki.
untuk mengaktifkan RIP:
config# router rip
untuk menyertakan directly connected network mana saja yang akan disebar:
config-router# network {classful-network-address | network-address}
Comman “network” punya dua fungsi yaitu:
1. mengaktifkan RIP di interface router yang ip-nya berada pada range classful network yang diinput
2. network yang diinput akan disertakan pada update packet sehingga akan tersebar
Masukkan saja classful network dibandingkan dengan network address karena RIP secara otomatis akan mengclassfulkan network address
Passive interface adalah interface yang hanya akan menerima update dari router lain, tetapi interface ini takkan pernah mengirimkan update. Sehingga, interface ini bisa ditujukan agar tidak menyebarkan update.
untuk mengaktifkan passive interface:
config-router# passive-interface interface-id
untuk menyebarkan static route:
config-router# redistribute static
untuk menyebarkan default route:
config-router# default-information originate
Router akan secara otomatis menjalankan route summarization pada boundary router.
Boundary router adalah router yang interfacenya memiliki ip address yang berbeda secara classful network
Auto-summary berjalan secara default dan tidak dapat di non-aktifkan

Pertama menkonfigurasi semua router dan kemudian memberi IP address yang sudah ada ke setiap PC, pada saat menkonfigurasi router pada configurasi routing menggunakan dynamic routing dan menggunakan classfull network address.
Kedua melakukan test apakah semua sudah terhubung dalam satu jaringan perhatikan gambar berikut :
1.     melakukan test  pada ketiga router apakah sudah terhubung dengan baik atau tidak
R1#ping 192.168.2.2 (R2)
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 31/31/32 ms
R1#ping 192.168.4.2 (R2)
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.4.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 31/34/47 ms
R1#ping 192.168.4.1 (R3)
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.4.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 49/59/63 ms
2.     melakukan tes pada setiap PC yang ada
PC1 ke PC2
Gambar 6.2 (PC1 ke PC2)
PC1 ke PC3
Gambar 6.3 (PC1 ke PC3)
Catatan : untuk ping ke PC lain saya tidak masukkan agar mengurangi besarnya ukuran memori file pada saat di upload di blog, gambar di atas sudah mewakili bahwa semua PC sudah terhubung.
 Setelah melakukan test ternyata semua item sudah terhubung dalam satu jaringan.
Hasil Praktikum
Setelah semua sudah dilakukan seperti inilah hasilnya :
1.      menverifikasi semua routing sudah masuk dan mengetahui informasi pada router dengan menggunakan command "show ip route", "show ip protocols", "debug ip rip".
