Hello All.

In Cisco, if I want to create a virtual interface in a router for inter VLAN routing. How I associate it to a physic port? Looking for some example on the internet I found.

Code:
conf t
interface g0/1
no ip address

!

interface g0/1.1
encapsulation dot1q 1
ip address 1.1.1.1 255.255.255.0

!

interface g0/1.2
encapsulation dot1q 2
ip address 2.2.2.2 255.255.255.0

If the virtual interface is interface g0/1.2 it-s means that is link with the physic port Gi0/1? And for example if it would be g0/0.2 that would means that it-s link the Gi0/0_

That is correct.

g0/1.1 is a subinterface of g0/1
g0/1.2 is a subinterface of g0/1

Each has been given a different vlan definition (dot1q) so if you have an existing vlan schema you would probably want to use that instead.
