Configuring PVPs

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).

Table3-3		VPIs for the Example PVP
	Switch A Switch B		Switch B	Switch C	Switch C	Switch D
	Out	In	Out	In	Out	In
Interface	3/0/2	0/0/0	1/1/1	3/1/1	1/0/0	0/1/1
VPI	3	3	5	5	8	8
