Laboratoriya ishi rip, eigrp, ospf va bgp protokollari asosida dinamik marshrutlashni sozlash

EIGRP protokol bo`yicha qurilgan tarmoq uchun ishni bajarish tartibi

6.6-rasmda tasvirlanga tarmoqda R1 va R2 routerlar o`rtasida axborot almashinuvini autentifikatsiyalash asosida va boshqa routerlar o`rtasida autentifikatsiyasiz sozlamalarni amalga oshiramiz, hamda ular o`rtasidagi farqlarni taqqoslaymiz.

BGP (ing. Border Gateway Protocol, chegaraviy shlyuz protokoli) Internetdagi asosiy dinamik marshrutlash protokoli hisoblanadi.
BGP protokoli boshqa dinamik marshrutlash protokollaridan farqli o‘laroq, marshrut ma’lumotlarini alohida marshrutlagichlar o‘rtasida emas, balki butun avtonom tizimlar o‘rtasida almashish uchun mo‘ljallangan va shu sababli, tarmoqdagi marshrutlar haqida ma’lumotlardan tashqari, avtonom tizimlarga yo‘nalishlar to‘g‘risida ham ma’lumot olib boradi.
