Configuring PVPs

A VP connection is like a bundle of VCs, transporting all cells with a common VPI, rather

than a specific VPI and VCI. A PVP is a provisioned VP (like a PVC).

Figure3-4 illustrates how to set up PVPs. This example network is used throughout this

section.

Figure3-4 Example Network for Configuring PVPs

Table3-3 describes the in and out interfaces and associated VPIs for the PVP shown in

Figure3-4. Between ATM switch routers, the VPIs for the out port and the in port must

match. For example, in Figure3-4, the VPIs match between ATM switch routers A and B

(VPI=3).

Note The VPIs for the internal crossconnects do not have to match. For example, in

Figure3-4, the VPIs do not match in ATM switch router A for the internal crossconnect

between ports 3/0/1 (VPI=2) and 3/0/2 (VPI=3).
