Provider Backbone Bridging through IEEE 802.1ad eliminates the need for tunneling BPDUs with L2PT
and increases the reliability of provider bridge networks as the network core need only learn the MAC
addresses of core switches, as opposed to all MAC addresses received from attached customer devices.
