Angelo,
You show see the PVC straight away.
If executing show atm pvc gives you nothing, then consider the following:
1st) the ATM switch must be configured with a PVC, I'm not sure if you have your own ATM switch or you are using a rental rack. If the latter, then some rental racks have the ATM switch preconfigured, some don't.
2nd) Some ATM switches do not support PVC discovery, the LS1010 (which is what you would use in the CCIE lab) does, the LS100 does not. Therefore, if using a rental rack source, find about about the ATM switch and what it supports.
Here is a sample ATM PVC config for an LS1010.
interface ATM0/1/1
no ip address
no ip directed-broadcast
no atm ilmi-keepalive
atm pvc 5 50 interface ATM0/1/0 6 60
The last line is saying that on ATM interface 0/1/1 the PVC is using a VPI/VCI pair of 5/50 and the other side of the PVC is using a VPI/VCI pair of 6/60 which is be routed out of ATM interface 0/1/1.
Thus, for router R1 that is connected to 0/1/1 you would expect to see VPI/VCI pair 5/50.
For router R2 that is connected to 0/1/0, you would expect to see VPI/VCI pair 6/60.
NOTE - You do not need another PVC statement on ATM0/1/0 that says that the VPI/VCI pair of 5/50 is routed out of ATM0/1/1.
In this respect, configuring ATM PVC's is different from configuring Frame-Relay PVC's.
Hope this helps you.
Andy

Thanks in Advance,
