Chapter7 Configuring Virtual Connections
Configuring PVP Connections
When configuring the route processor leg of a PVC that is not a tunnel, the VPI should be configured as
0. The preferred method of VCI configuration is to sele ct the any-vci parameter, unless a specific VCI
is needed as a parameter in another command, such as map-list.
Note If configuring a specific VCI value for the route processor leg, select a VC I value higher than 300 to
prevent a conflict with an automatically assigned VCI for well-known channels if the ATM switch router
reboots.

Displaying the Terminating PVC Connections

To display the terminating PVC configuration VCs on the interface, use the following EXEC command:
See Displaying VCCs, page 7-4 for examples of the show atm vc commands.
Configuring PVP Connections
This section describes configuring a permanent virtual path (PVP) connection. Figure 7-3 shows an
example of PVPs configured through the ATM switch routers.
