A P box does label swapping, PE boxes do label imposition/disposition. I
don't think any MPLS-enabled router (Cisco or otherwise) that can act as
a PE box can't also be used as a P box. Even though theoretically it
would be possible. (And a lot of boxes can be P but not PE.)

A lot of enterprise MPLS VPN setups (smallish) use no dedicated P boxes,
they just have the PE boxes in a ring or some kind of mesh.
