Re: MLPPP over MPLS

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.

Greetings all,

Would anyone who has every done MLPPP over MPLS care to share their experiences with this type of network?

We have a customer that is implementing an MPLS network that will have 2 to 6 T1 feeds at some locations that will be 
using MLPPP for channel bonding. This is a telco provided network that will be customer managed. 

The routers will be customer managed because the same equipment will have interfaces to another telco's network as a 
backup to the MPLS network. Needless to say, no telco will support equipment that interfaces competitors networks.

The customer is being told by their router vendor that an MLPPP/MPLS network is 'too complex' to be managed by anyone 
except for the router vendor's VARs or the telco. 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.

This doesn't sound like rocket science to me -- it should be simple and rather straight forward, I would think: The 
telco specifies its requirements for the router configuration, the customer implements that configuration on the 
required router interfaces, the telco monitors line quality, and the customer does basic router monitoring. 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?

Thanks in advance for your feedback!
