ATM routing uses a two-layer hierarchical scheme, virtual paths, and virtual
channels, denoted by the virtual path identifier (VPI) and virtual channel
identifier (VCI), respectively. A particular virtual path may carry a number of
different virtual channels corresponding to individual connections. When
switching is performed based on the VPI, all cells on that particular virtual path
are switched regardless of the VCI. An ATM switch may route according to VCI,
VPI, or both VCI and VPI.
Enter the VPI value obtained from your service provider or system administrator.
The virtual path identifier (VPI) is used in ATM switching and routing to identify
