Laporan Jaringan Komputer 7
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 sama seperti saat mengkonfigurasi
router pada skenario A, akan tetapi di skenario B ini menyediakan IP yang sudah
di subnetting otomatis untuk RIP pada skenario A diganti dengan IP yang sudah
di subnetting caranya ada command di router menggunakan perintah "no ip route".
Perintah tersebut berlaku pada ketiga
router "no ip route" adalah perintah yang digunakan untuk menghapus "ip route" sebelumnya pada
skenario ini kita disuruh menghentikan update ip pada setiap router command
yang digunakan "passive-interface
fastethernet0/0".
Kedua melakukan test
apakah semua sudah terhubung dalam satu jaringan perhatikan gambar berikut :
1.
Melakukan test koneksi pada setiap router
apakah sudah terhubung
R1#ping 172.30.2.2 (R2)
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.30.2.2,
timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip
min/avg/max = 1/7/24 ms
R1#ping 192.168.4.9 (R2)
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.4.9,
timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip
min/avg/max = 10/18/20 ms
R1#ping 192.168.4.10 (R3)
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.4.10,
timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip
min/avg/max = 33/38/40 ms
2.
Melakukan test koneksi pada ketiga PC apakah
sudah terhubung.
PC1 ke PC2
Gambar 7.2 PC1 ke PC2
PC1 ke PC3
Gambar
7.3 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 koneksi pada semua item ternyata semua 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".
