[nsp] QoS issues with LLQ, Fair Queue and Frame Relay

[Eric Wieling]

I'm having trouble with getting QoS working.  I looked at
http://www.cisco.com/en/US/tech/tk652/tk698/technologies_configuration_example09186a0080094af9.shtml and decided to go withLLQ rather than IP RTP Priority because we will eventually want to prioritize traffic in addition to RTP traffic.  What I'm seeing is that the RTP traffic is NOT being prioritized over other traffic.  I'm also seeing what looks like random problems with TCP connections (users are complaining about not being able to connect to our mail server, etc.

We have a Frame Relay network in a hub and spoke configuration.  QoS was
configured at each of the offices.  

I've pasted part of our config in hopes that someone out there can see
what I might be doing wrong.  ANY help or pointers to additional
information would be helpful.
