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
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
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
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".
