Could it possibly be due to the fact you don’t have a bandwidth statement on the ATM interfaces ?
I just lab’d your config and added the bandwidth statement and it works for me

Dear All,
I am workig on MLPoATM the real scenerio is like that one side of the ckt i have DS3 and on the other side i have DSL. What I need to do is to bundle the DSL links using MLP. Since I cannot do this on live ckt, i tried to this simulation using ATM on Dynamips used (2)7200 PA-A1 module on both sides. The VBR-NRT command is not supported on this module and since its an optional i leave this in testing.
I followed the cisco documention of configuring MLPoATM. I am able to ping end-end. but still when i issue “show ppp multilink” i am unable to see the bandwidth bundled up. When I issue ” show policy-map int” I see them combine and when i shut down one atm linke on R2, it reduces to half of it. Why I am not seeing it in first command.
Am I missing something in my configuration? Please let me know.
Here is the Conf.
