SuperSpan
SuperSpan is an HP STP enhancement that allows Service Providers (SPs) to use STP in both SP networks and
customer networks. The SP devices are HP devices and are configured to tunnel each customers' STP BPDUs
through the SP. From the customer's perspective, the SP network is a loop-free non-blocking device or network.
The SP network behaves like a hub in the sense that the necessary blocking occurs in the customer network, not
in the SP.
The HP interfaces that connect the SP to a customer's network are configured as SuperSpan boundary interfaces.
Each SuperSpan boundary interface is configured with a customer ID, to uniquely identify the customer's network
within SuperSpan.
Figure 6.1 shows an example SuperSpan implementation. In this example, an SP's network is connected to
multiple customers. Each customer network is running its own instance of standard STP. The HP devices in the
SP are running SuperSpan.
