Basic ATM Interface Configuration

I thought ATM interfaces are configured just like any other juniper interface. How stupid I was :)
I got this error message:

So JUNOS needs us to specify the ATM PIC type and the VPI/VCI number.

Configuring the ATM PIC Type
#set atm-options pic-type atm2

Configuring the VPI
#set atm-options vpi 0

Configuring the VCI
#set unit 100 vci 100

I chose the VCI number identical to the unit number; it's just a best-practice.

Configuring the IP address
#set unit 100 family inet address 10.0.16.2/24

and don't forget to commit.
