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 select 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 VCI 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.
