RIP termasuk protokol distance vector, yang berarti ia menentukan jalur terbaik berdasarkan hop count. Mesin-mesin yang ikut berpartisipasi dalam RIP bisa termasuk aktif atau pasif RIP. Active RIP berupa router-router yang berpartisipasi dalam proses pertukaran data distance vector. Mesin-mesin Active RIP mengirimkan tabel routingnya kepada router lain dan memantau update dari router lain. Mesin passive RIP hanya memantau update tapi tidak ikut menyebarkan tabel routingnya. Mesin ini biasanya berupa komputer klien.
Jika ada dua jalur dengan network tujuan yang sama dan hop count yang sama maka router akan memilih jalur yang terlebih dahulu ada didalam tabel routing. Router RIP membroadcast pesan update setiap 30 detik. Jika jumlah router-router terlalu banyak akan timbul masalah karena akan memperlambat waktu convergence. Untuk itu, RIP membatasi angka maximum hop count sebesar 15. (sumber)

- Interface Vlan Tagging
Interface Vlan Tangging
set interfaces em0 vlan-tagging
set interfaces em1 vlan-tagging
set interfaces em2 vlan-tagging
set interfaces em3 vlan-tagging
Konfigurasi Interface Vlan tagging berfungsi untuk menghidupkan fungsi “vlan” pada interface. vlan tersebut berguna untuk penghubung virtual antara interface sebuah router dengan router lainnya. Jika anda tidak mengkonfigurasi interface vlan-tagging, maka konfigurasi tidak akan dapat dijalankan meskipun anda sudah memberikan vlan-id pada setiap interface.
