Handling Process
The transmission transparent of VP means that the database messages are transmitted transparently according to the VPI message of users. Generally speaking, the transmission transparent of PVC transmits the message transparently according to the VCI of users. The transmission transparent of PVC can only transmit the message of ATM in type of AAL5 transparently. But for the forepart network, some banks or enterprise of finances have the operations of FR, so it exist the cases that we need to transmit the ATM in type of AAL1 transparently, now we need the transmission transparent of VP to realize it.  
Such as, transmit the PVC in the interface of 8/32 under the ATM1/0/5 to the interface of 8/59 under the ATM1/0/7 transparently according VP, the configurations are as follows:
interface Atm1/0/5.100                                                         
undo shutdown                                                                 
pvp 8                                                                         
  undo shutdown                                                                
#                                                                             
bas                                                                           
  access-type layer2-relay-leased-line 
interface Atm1/0/7.100                                                         
undo shutdown                                                                 
pvp 8                                                                         
  undo shutdown                                                                
#                                                                             
bas                                                                           
  access-type layer2-relay-leased-line 
vp-relay inport Atm1/0/5 pvp 8 outport Atm1/0/7 pvp 8 

The notices of configurations for the transmission transparent VP:
1. If we need to transmit the VPC with witch the VPI is 8 transparently by VP, all of the VPC with the VPI is 8 will be transmitted transparently by VP under the same physical interface. In this case the PVC with the VPI is 8 can’t use the PPPoE or others operations.
2. The transmission transparent VP need to be configured under an unattached sub-interface or a main interface, and this interface can’t be configured with other types of PVC.
3. When we configure the transmission transparent for VP-RELAY, the interface must be the main interface; even the PVP is configured under the sub-interface.
