What tunneling mode should I be using in my QoS implementation in a SP environment? We run only MPLS L3 VPNs.
I know the differences between the tunneling modes but can't figure out which one to use.
Ideally we want to preserve the customer's markings so I wasn't sure as the SP we look at implementing pipe mode (PE Edge (to CE) policies are based on
provider markings) or short pipe mode (PE Edge (to CE) policies are based on customer markings).
What do I need to look at to help me make my decision?
