Marshrutizatsiya protokoli optimal yo‘llar orqali marshrutizatsiya jadvalini to‘ldirish va marshrutizatsiya ma’lumotlarini almashish uchun ishlatiluvchi xabarlar va algoritmlar, jarayonlar to‘plamidan iborat. Dinamik marshrutizatsiya protokollari quyidagi maqsadlarda ishlatiladi: uzoqdagi tarmoqlarni aniqlash; marshrutizatsiya ma’lumotlarini yangilash; ko‘rsatilgan tarmoqqa optimal yo‘lni tanlash; ishlab turgan yo‘lga kirish mumkin bo‘lmagan yangi optimal yo‘lni izlash. Dinamik marshrutizatsiya protokollari quyidagi komponentlarni o ‘ z ichiga oladi: ma’lumotlarning tuzilishi - marshrutizatsiya protokollarini ishlashi uchun ma’lumotlar bazasi yoki jadval ishlatiladi. Ushbu axborot operativ xotira qurilmasida saqlanadi; marshrutizatsiya protokolining xabari - marshrutizatsiya protokollari marshrut to‘g‘risida axborotlarni almashish, qo‘shni marshrutizatorlarni aniqlash, tarmoq to‘g‘risida muhim axborotni olish bilan bog‘liq bo‘lgan boshqa vazifalarni bajarish uchun turli xabarlarni ishlatadi; algoritm - algoritm topshiriqlarni bajarish uchun ishlatiluvchi harakatlar ruyxatidan iborat. Marshrutizatsiya protokollari optimal yo‘lni aniqlovchi va marshrntizatsiya ma’lumotlarini almashishni soddalashtiruvchi algoritmlami ishlatadi. RIP protokoli: administratomi minimum darajadagi nazoratini talab qilish maqsadida marshrntizatsiya jadvalini tuzish uchun ishlab chiqilgan; ma’lumotlarni qayta ishlashda marshrutizatorlarda yuklanishni kamaytirish maqsadida guruhli manzil bo‘yicha jo‘natiladigan xabar marshrutizatorlar o‘rtasida almashiladi; ichki domenli va masofa - vektor protokoli bo‘lib, Bellman - Ford algoritmiga asoslangan; ko‘rsatilgan joyga masofani belgilashda metric ko‘rsatkichi ishlatiladi (sonli ko‘rinishda); 15 tagacha marshrutizator bo‘lgan o‘rtacha tarmoqlarda ishlatiladi; RIP xabari UDP (520 port)ga inkapsulyasiya qilinadi va tarmoqda o‘zgarish bo‘lmasa ham har 30 daqiqada jo‘natilaveradi; autentifikatsiyani talab qilmaydi (foydalanuvchini registratsiya axborotini tekshirishni amalga oshiruvchi kirishni nazorat qiluvchi servis).
