Router ! ! switch ! !-- VLAN10----- PC1 ! -----PC2 ! !--VLAN20------PC3 ! ------PC4 ! !--VLAN30------PC5 VLAN10 & VLAN20 SHOULD NOT COMMUNICATE EACH OTHER. VLAN30 SHOULD ABLE TO ACCESS BOTH VLAN10 & VLAN20. ROUTER SHOULD ABLE TO PING ALL PCS. How do i configure this. pleas provide the step by step information.
