A specific case is the format of the packet used to transport user traffic between PE-rs and MTU-s
devices in the H-VPLS architecture. In this particular case, MTU and PE devices are directly
connected to each other over a Layer 2 connection. Consequently, a transport label is not needed.
The packet format is shown in
Figure 7
