• Enabling communication between different VLANs using switches

    I have 3 switches A, B and C; connected to each other (may or may not be a trunk link). Switch A has a user at VLAN 10 and Switch C has a user at VLAN 10. Any communication between A & C has to pass through Switch B. So can Switch A user ping the user at Switch C, if yes how? if no why?
