1. Set IP and Subnet in each PC, according to the image above
2. On Switch:

> enable
# configure terminal
(config)# interface FastEthernet 1/1
(config-if)# switchport mode access
(config-if)# switchport access vlan 2
(config-if)# no shutdown

(config-if)# interface FastEthernet 1/24
(config-if)# switchport mode access
(config-if)# switchport access vlan 3
(config-if)# no shutdown

(config-if)# interface FastEthernet 1/2
(config-if)# switchport mode trunk
(config-if)# switchport trunk allowed vlan 2
(config-if)# switchport trunk allowed vlan add 3
(config-if)# no shutdown
(config-if)# (*press ctrl-z)
# write

3. On Router:

> enable
# configure terminal
(config)# interface Ethernet 0
(config-if)# no shutdown

(config-if)# interface Ethernet 0.1
(config-if)# encapsulation dot 1Q 2
(config-if)# ip address 192.168.1.1 255.255.255.252

(config-if)# interface Ethernet 0.2
(config-if)# encapsulation dot 1Q 3
(config-if)# ip address 192.168.1.5 255.255.255.252
(config-if)# (*press ctrl-z)
# write

Shouldn't be any problem, I hope :)
