The question is How do I mark 1918 traffic so my vendor can prioritize this traffic over 1918 traffic without messing up my voice traffic?
We have MPLS connectivity where the Public and Private (Voice and Data) traffic travel across the same WAN links.
One suggestion is to prioritize enterprise (1918) traffic over Internet traffic.
To accomplish this task, we have to mark the 1918 traffic on our router.
Would I add a class map to my existing policy map whic is applied to my interface using a service policy?
Any input is greatly appreciated.

Before you do anything, are you sure that you MPLS provider supports different classes of service ?
Not all do.

Yes, the MPLS provider supports different class of service. They stated, if we can mark it, they can prioritize it. Today, we have four different planes.

Then just look an example of DSCP marking.
You can use any criteria you like. Some voice traffic comes already marked.
