Why do we configure loopback interface on router?

Do you need a loopback interface in a Cisco switch?

Loopback interfaces do not have internal VLAN IDs or MAC addresses. With Layer 2 Cisco switches like the 3500XL or 2950, a loopback interface is not needed since these switches are not capable of routing between interfaces. The management VLAN of the switch acts like the loopback interface since they are both logical interfaces.
