Dell S4048T User Manual

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.
• Use the Provider Bridge Group address as the destination MAC address in BPDUs. The xstp keyword
applies this functionality to STP, RSTP, and MSTP; this functionality is not available for PVST+.
