Figure 3 - Supporting LSPs in the Private-Public-Private Architecture
Figure 4 shows the architecture for a corresponding solution applied to the architecture of
Figure 2. As in Figure 3, an extra NAT/FW device has been placed at the data center edge. This
FW device must be VLAN supported in order to support overlapping address spaces for different
LSPs in different enterprises. However, unlike Figure 3, no changes are needed to the equipment
at the edge of the enterprise site since there is no change in address space at that point.
