VLAN lar o‘rtasida marshrutizatsiyani sozlash

Lokal tarmoqda yaratilgan VLAN lar o‘rtasida marshrutizatsiyani sozlashning 3 xil usuli mavjud:

• 
  Demonstrating the legacy inter-VLAN routing.
  
• 
  Router-on-a-Stick
  
• 
  Switch Based Inter Vlan Routing
  

Bu laboratoriya ishida VLAN lar o‘rtasida marshrutizatsiyani Router-on-a- stick (ROS) usulidan foydalanamiz.

5.3-rasm. VLAN o‘rtasida marshrutizatsiyalashning ROS usuli

Sw1(config)#interface fastEthernet 0/8 Sw1(config-if)#switchport mode trunk

Router>enable Router#conf t

Router(config)#interface fastEthernet 0/1 Router(config-if)#no shutdown Router(config)#interface fastEthernet 0/1.10 Router(config-subif)#encapsulation dot1Q 10
Router(config-subif)#ip address 192.168.10.254 255.255.255.0 Router(config-subif)#exit
Router(config)#interface fastEthernet 0/1.20 Router(config-subif)#encapsulation dot1Q 20
Router(config-subif)#ip address 192.168.20.254 255.255.255.0 Router(config-subif)#exit
Router(config)#interface fastEthernet 0/1.30 Router(config-subif)#encapsulation dot1Q 30
Router(config-subif)#ip address 192.168.30.254 255.255.255.0 Router(config-subif)#exit

2 - topshiriq bo`yicha qisqacha nazariy ma’lumot

VTP (ingliz. VLAN Trunking Protocol) - lokal hisoblash tarmog`i protokoli bo`lib, tanlangan trank portda VLAN haqida axborot almashish uchun xizmat qiladi. VTP – vlan larni dinamik tarzda sinxronizatsiyalash uchun ishlatiladi;
3 xil rejimi mavjud:
1.Client – VLAN larni o`zgartirish, o`chirish, yaratish mumkin emas; 2.Transparent – bunda, switch da sinxronizatsiya amalga oshirilmaydi,
switch faqat o`tkazuvchi vazifasini bajaradi;
3. Server – VLAN bilan istalgan funktsiyalarni bajarish mumkin;
Vtp serverda vlan yaratiladi Clientlar avtomatik serverda yaratilgan VLAN larni qabul qiladi. Xavfsizlik ta ‘minlash maqsadida bu protokolda Client switch vlan yarata olmaydi, faqat foydalanuvchilarni o`zlariga biriktira oladi. Tarmoqda qandaydir o’zgarish yuz bersa (masalan yangi vlan qo`shilishi yoki olib tashlash) faqat VTP server orqali amalga oshiriladi.
VTP-da uchta xabar turi mavjud:
