Konfigurasi Network Routing RIP (Simulasi Packet Tracer)

Ok… kali ini saya bahas mengenai RIP ( Routing Information Protocol) pada router Cisco. Langsung bahas percobaannya saja… teorinya belakangan. Saya ambil contoh kembali network sebelumnya, yang menggunakan static routing. Static routingnya diganti dengan RIP, sehingga nanti akan lebih mudah untuk melihat perbedaannya.

	ROUTER JKT	ROUTER-SBY	ROUTER MTR	ROUTER-MLK
Fa 0/0	10.10.11.1/24	10.10.22.1/24	10.10.33.1/24	10.10.55.1/24
Fa 1/0	-	-	10.10.44.1/24	-
Comp User	Dhcp	Dhcp	Dhcp	Dhcp
Fa 4/0	192.168.1.1/30	192.168.1.2/30	192.168.3.1/30	192.168.3.2/30
Fa 5/0	-	192.168.2.1/30	192.168.2.2/30	-

Untok konfigurasi interface dan DHCP, pada routernya, saya rasa sudah dicontohkan dan dijelaskan pada posting sebelumnya tentang static routing. Jadi bisa dilihat sendiri pada postingan sebelumnya, dan tidak perlu saya bahas lagi disini. Langsung saja pada bagian konfigurasi RIP nya.

Sedikit penjelasan tentang command konfigurasi RIP.

• router rip, mulai mengkonfigurasi routing RIP.
• version 2. Versi RIP yang baru. Biasanya versi baru kan harus lebih baik dari versi sebelumnya.
• network 192.168.1.0. Ingat yang dimasukkan adalah Network ID dari IP address si router yang terkoneksi dengan router lain yang akan menggunakan routing RIP.
• redistribute connected, Command ini ditambahkan karena ada beberapa IP address yang terkoneksi langsung dengan router, yang tidak menggunakan routing RIP. Contohnya seperti IP address dari user/computer yang langsung terhubung ke router
• no auto-summary, list / table routingnya akan dibuat terperinci, tidak dibuat secara umum. Lihat perbedaan antara “auto-summary” dengan “no auto-summary” dengan mengunakan perintah “sh ip route”.

Berikut contoh hasil “sh ip route” jika command auto-summary digunakan pada routing rip.

#sh ip route

Codes: C - connected, S - static, I - IGRP, 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, E - EGP

       i - IS-IS, 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

Gateway of last resort is not set

     10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

R       10.0.0.0/8 [120/1] via 192.168.1.1, 00:00:04, FastEthernet4/0

C       10.10.22.0/24 is directly connected, FastEthernet0/0

     192.168.1.0/30 is subnetted, 1 subnets

C       192.168.1.0 is directly connected, FastEthernet4/0

     192.168.2.0/30 is subnetted, 1 subnets

C       192.168.2.0 is directly connected, FastEthernet5/0

     192.168.3.0/24 is variably subnetted, 2 subnets, 2 masks

R       192.168.3.0/24 [120/1] via 192.168.2.2, 00:00:11, FastEthernet5/0

R       192.168.3.0/30 [120/2] via 192.168.2.2, 00:00:11, FastEthernet5/0

Pastinya router akan bingung, untuk mengirimkan packet kemana, karena semua komputer pada contoh di atas menggunakan segmen IP class A, 10.0.0.0. dan pada table routing di atas hanya ada 10.0.0.0/8 via 192.168.1.1.
Berikutnya, di bawah ini hasil sh ip route, jika menggunakan command “no auto-summary”.

ROUTER-SBY#sh ip route

Codes: C - connected, S - static, I - IGRP, 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, E - EGP

       i - IS-IS, 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

Gateway of last resort is not set

     10.0.0.0/24 is subnetted, 5 subnets

R       10.10.11.0 [120/1] via 192.168.1.1, 00:00:16, FastEthernet4/0

C       10.10.22.0 is directly connected, FastEthernet0/0

R       10.10.33.0 [120/1] via 192.168.2.2, 00:00:18, FastEthernet5/0

R       10.10.44.0 [120/1] via 192.168.2.2, 00:00:18, FastEthernet5/0

R       10.10.55.0 [120/2] via 192.168.2.2, 00:00:18, FastEthernet5/0

     192.168.1.0/30 is subnetted, 1 subnets

C       192.168.1.0 is directly connected, FastEthernet4/0

     192.168.2.0/30 is subnetted, 1 subnets

C       192.168.2.0 is directly connected, FastEthernet5/0

     192.168.3.0/30 is subnetted, 1 subnets

R       192.168.3.0 [120/1] via 192.168.2.2, 00:00:18, FastEthernet5/0

Terlihat jelaskan perbedaanya ? Jadi itulah kegunaan dari “no auto-summary”, akan dibuat table routing terperinci. Ok. Saatnya untuk mencoba, test ping dari salah satu komputer.

Sampai disini, simulasi network dengan packet tracer sudah berhasil mengkoneksikan network dengan menggunakan routing RIP. Di lain kesempatan akan dibahas tentang teorinya,…
