Nima uchun kerak?

VLAN'lar bir-biridan ajratilgan bo‘ladi. Ular orasida aloqa uchun Layer 3 routing kerak. Router-on-a-stick usulida router va switch orasida trunk ishlatiladi.

interface g0/0
 no shutdown
interface g0/0.10
 encapsulation dot1Q 10
 ip address 192.168.10.1 255.255.255.0
interface g0/0.20
 encapsulation dot1Q 20
 ip address 192.168.20.1 255.255.255.0

Switchdagi routerga ulangan port trunk bo‘lishi kerak. Har bir VLAN uchun gateway sifatida tegishli subinterface IP manzili ishlatiladi.
