I've created my own lab to test out the different types of Layer 2 protocols I can transport over MPLS.
There are, at a basic level, 2 parts to enabling AToM. First, create a pseudowire-class and second, create the VC via an xconnect statement under the CE facing interface on the PE.
Of course, the prerequisite for this to work is that MPLS is enabled throughout the core network.
Also, note that to make life easier use 'mpls ldp router-id loop 0 force'. You have to designate the other PE as peer in xconnect which will be the ldp router id.
Layer 2 protocols that can be transported are EoMPLS, FRoMPLS, PPPoMPLS, HDLCoMPLS, and ATMoMPLS (can't emulate in dynamips, as the PA-A1 doesn't support it).

CE config
The CE's are generally configured like back to back CE to CE connections with nothing but a pseudo wire connecting the two. * Remember for FRoMPLS though, you'll want once side to act as Frame switch and that interface to be DCE.
