Our engineering staff has been asked to provide QoS priority for multicast video over an ASR 10G backbone network. We use sub-interfaces to separate Internet, video, and MPLS traffic on our backbone. What is the best method to provide QoS priority for video in the example configuration below?
Do we need to mark traffic at ingress and then apply an outgoing policy to the 10G primary interface?
Is there a way to provide priority for a sub-interface in IOS-XR?
We are using IOS-XR 5.3.3 currently.
