Either should work. Have you actually tested it to see the results?

Suppose you have the following diagram, R1-----R2------R3 (Link between R2 and R3 is frame relay) Each router is configured with mpls and an IGP. R1 is sending traffic with an mpls exp of 4 and R2 is matching the traffic and setting a priority bandwidth on the output interface of R2 towards R3. How should the MQC configuration be applied on the frame relay interface? For example "service-policy output POLICY" directly on the frame-relay interface or do you use a map-class via frame-relay traffic shaping to apply the service policy command? For example: class-map EXP4 match mpls exp top 3 ! policy-map POLICY class EXP4 band 1000 ! int serial 2/0 frame-relay traffic shaping frame-relay class 304 ! map-class frame-relay 304 frame-relay cir 45000000 service-policy output POLICY ! Basically what I would like to know is one way wrong and the other correct? Does it matter if the frame-relay is in a subinterface? Thanks for the help Stevan
