Hello Vicky,

you can implement QoS on a point to point link the mechanism to be used is Class Based Weighted Fair Queueing with Low Latency Queue.

the low latency queue is a priority queue that you should use for VoIP RTP packets.

you can use modular QoS to define traffic classes and you associate each traffic class with a queue.

the resulting policy-map is applied outbound on the point-to-point interface

You can reuse config templates for MPLS facing links. The configuration has to be performed outbound on both sides of the link.


Hope to help
