Rodney,
It's running: 12.4(18a). I had to downgrade from the latest about 6
months ago because of a bug where 'show policy' would show no output
even if QoS was working properly.

Does that mean that there's no processor switching going on there? Why
would a VRF make any difference to the MLPPP? I see the same outputs
for a non VRF'd MLPPP.

You have it in a VRF which really shouldn't cause an issue as it's
tag2ip and ip2tag.
What code is it?
Make sure it's the latest 12.4 mainline as we did some work in 12.4 to make
this work.
Can you get a 'sh int mul 2 stat' after a clear counters...get it a few
times and send it?
Also, what are the other interface configs feeding this bundle?
It could be features on them causing the punts.
What does 'sh cef int' say?

The G1's with MLPPP should not be process switching the traffic.
What is the config?
The EC cards just offload the MLPPP to the new asic on the PA.

Greetings,
I've got a 7206VXR NPE-G1 with a bunch of DS3 cards in it (PA-MC-T3).
There's about 25 multilinks with an average of 2 T1s per bundle. I see
a lot of process switching on the router and I have a feeling it's
because we don't have the PA-MC-T3-EC card so the processor has to step
in for the MLPPP.
Is this the case? If I get some PA-MC-T3-EC cards to swap in, will that
take a lot of load off the NPE-G1? Any output needed, please let me know.
Thanks,
Jason
