What I heard from Cisco is that there may be some issue with MLPPP and
MPLS - maybe QoS? -.
The issue is for general IOS support issue for MLPPP/MPLS combination.
For that reason, Cisco recommended Multi-link Frame Relay(MLFR) to
overcome that issue.

They indicated that it would be impossible for the customer's router vendor certified network person to come up to speed on MLPPP/MPLS configurations and manage such a network -- that it takes years to adequately learn how to manage that type of network configuration.

Am I missing something here, or is the router vendor just blowing a lot of smoke to try to provide business for some of his clients that provide managed services?
