A service provider offers four classers of service for MPLS VPN customer with the following IPP/EXP values.
i. voice = 5
ii. video = 4
iii. priority-data = 3
iv. best-effort data = 0
The service provider also supports multicast VPN services in the priority data and best-effort classes. Multicast VPN is implemented as a draftrosen profile. On a P router, in the MPLS core, the ingress Qos policy-map must classify all incoming packets, so that different classes of traffic can be properly handled in fabric queues and egress queues. All types of packets in the core network must be covered.
Which ingress classification offers the optional performance and provides the minimum number of actions that match the service provider QoS requirements?
