    Tarmoq topologiyasini tuzish.

    Ishni bajarish bo‘yicha topshiriqlar:
    Har bir talaba sanab o‘tilgan tartib raqami bilan berilgan variantlardan birini tanlashi kerak
    1-jadval va quyidagi vazifalarni bajaring:

    1. Har bir marshrutizator ostida ikkita kalit bo‘lishi kerak, ular router orqali ulanadi.

    2. Har bir kommutatorda kamida ikkita turli VLAN guruhini tashkil qiling (masalan: kommutator_1 uchun VLAN_2, kommutator_1 uchun VLAN_3, kommutator_2 uchun VLAN_2, VLAN_3). Har bir VLAN guruhida kamida ikkita kompyuter (kompyuter) bo‘lishi kerak. Har bir VLAN guruhi bittasi bilan ma’lumot almashishi uchun kalitlar o‘rtasida TRUNKni joylashtiring.

    3. Yaratilgan tarmoqda marshrutlash protokollarini qo‘llash uchun 1-jadval 3-ustuniga qarang.

    4. Kompyuter qurilmalariga IP addresslarni berishda dinamik addresslarni taqsimlash protokolidan (DHCP) foydalaning.

    5. VLAN guruhlari boshqa tarmoqdagi VLAN guruhlari bilan ma’lumot almashishiga ishonch hosil qiling. Ushbu vazifani 1-jadvalning 6-ustunida keltirilgan marshrutizatorlar uchun qo‘llang.

    5-ustunda keltirilgan marshrutizatorlar uchun 1-jadval, konsolga kirish, imtiyoz rejimiga kirish, shuningdek masofaviy kirish uchun passwordni o‘rnating (password sifatida ismingiz, familiyangiz va sherifingizdan foydalaning).
