I'm using Boson sim. On one router's ethernet interface I have conected switch with two hosts. Every host belongs to diffrent vlan ( VLAN 2 , VLAN3). So I configure subinterfaces in router with diffrent network address ( ethernet 0/0.2 --> 192.168.1.1 ; ethernet 0/0.3--> 192.168.2.1 ). But I left physical ethernet 0/0 without address ( can I ? ). I used 'no shutdown' command on evry subinterfaces. Now I try ping those addresses and it doesn't work. I have no reply. Is anybody now what is wrong?
P.S. I am beginer and sorry for so simple question (probly) :)
