Hello Sam,
That is a good question.
I am going to go with only when there is a congestion. Since LLQ is just priority queuing on top of CBWFQ, and for any of these methods, the default should be FIFO unless there is congestion.
And when I say congestion, what I mean is, as long as there are 2 packets contending for the same exiting interface, then that is congestion for this discussion.
If 2 packets never contend for the same exiting interface at the same time and nothing in the buffer, then no queuing is needed. That is my guess..
I would also like to hear from better experts in this subject and see what others thoughts are on it.
thanks,
Paul

I know that any queuing technique does not kick in unless there is a
congestion in the router. Is that also true for IP RTP priority and LLQ? I
mean does the router send the voice packets to the priority queue or the
configured priority class to priority queue all the time or if there
congestion only? I hope that my question is clear. Please let me know if you
need more clarification. Thanks.
Sam
