[rbak-nsp] Accepted way to shape L2TP subscribers

Collective,

Wondering on the commonly accepted way of shaping L2TP subscribers.

Currently am using a PWFQ policy such:

qos policy RATECAP24M pwfq
 rate maximum 24576
 num-queues 4
 queue 0 priority 0 weight 100
 queue 1 priority 1 weight 100
 queue 2 priority 2 weight 100
 queue 3 priority 3 weight 100
!

Though I understand that this is achievable with both metering and
policing policies.

Wondering what the best way to do this is, considering I would rather
shape than police (i.e be kind to TCP and avoid bandwidth "sawtooth"
oscillations caused by TCP not backing off)

Was thinking of switching to metering simply to be able to add
marking to the policy as well.

Any advice appreciated.

Dave.
