Cisco : Dynamic Routing - RIPv2
Cisco RIP (Routing Information Protocol): Adalah salah satu protokol dynamic routing yang paling sederhana dan sering digunakan. RIP menggunakan algoritma distance vector untuk menghitung jarak menuju suatu jaringan, yang diukur berdasarkan jumlah hop (lompatan) yang harus dilalui oleh paket data.
Syntax
RIPv1 configuration
| Command | Description |
|---|---|
R1(config)#router rip | masuk ke mode routing dengan rip sebagai |
R1(config-router)#network [network-id] | Menspesifikasikan network address. tanpa subnetmask/wildcard |
R1(config-router)#passive-interface [int-id] | (optional) - mencegah interface meniklankan rip routing update |
Untuk alasan keamanan, interface yang TIDAK perlu mengirim update RIP (misalnya, interface yang menghadapi segmen jaringan dengan host dan bukan router lain) harus dikonfigurasi sebagai pasif. Ini merupakan praktik yang baik karena pembaruan RIP pada segmen ini hanya akan membuang-buang bandwidth.
Seperti yang Anda lihat, TIDAK ADA informasi subnet mask yang dikonfigurasi. Saat meneruskan update, router menggunakan mask yang dikonfigurasi pada antarmuka lokal atau mask default berdasarkan kelas alamat (A, B, atau C).
Karena itu, jaringan Anda pada skema RIPv1 ** HARUS KONSISTEN**, yang berarti bahwa VLSM atau supernetting tidak didukung oleh RIP versi 1
RIPv2 configuration
| Command | Description |
|---|---|
R1(config)#router rip | masuk ke mode routing dengan rip sebagai |
R1(config-router)#version 2 | Mengubah versi RIPv1 mennjadi RIPv2 |
R1(config-router)#no auto-summary | disable network auto summarization |
Topologi
Hubungkan semua segment jaringan dengan rip
