cisco 1721 router on a stick

ciscomeo,

It should work, you will know if it does not allow you to setup the sub-interface or you can not do the encapsalation.

interface FastEthernet0.3
description VLAN 3
encapsulation dot1Q 3
ip address 192.168.3.1 255.255.255.0
!
interface FastEthernet0.4
description VLAN 4
encapsulation dot1Q 4
ip address 192.168.4.1 255.255.255.0
!
interface FastEthernet0.5
description VLAN 5
encapsulation dot1Q 5
ip address 192.168.5.1 255.255.255.0

Hope this helps!!
