Hi Jason,
You hit the best article I've found on CCO on the topic. If I understand
you correctly, you're looking to do just LLQ for a class of traffic. The
problem with that is you need to induce "back pressure," which is
essentially artificial congestion in order for your LLQ to kick in. So to
my knowledge, you do need to do hierarchical QoS with LLQ as a child policy.
Otherwise, your logical tunnel interface never experiences congestion and
thus your LLQ doesn't do you a heck of a lot of good...
Regards,
Scott

Subject: QoS Over GRE
does anyone have any experience in doing priority-queuing over GRE tunnels?
I found an article by Cisco, but I can't say that it's all that I'm looking
for.
I don't want to do any QoS other than priority-queuing over the tunnels
unless required.
Here's the one link I found:

...looking for more.
