Configuration On The Ingress Router - Juniper BGP - CONFIGURATION GUIDE V 11.1.X Configuration Manual

JUNOSe 11.1.x BGP and MPLS Configuration Guide
The scheduler and queue profiles are referenced in QoS profiles. For example, you
can create a QoS profile for port-based per-class queuing or for LSP-level per-class
queuing (configuration omitted).
You must map the PHB IDs to the appropriate traffic class/color combinations:

Configuration on the Ingress Router

You must access the tunnel interface to map the PHB IDs to the EXP bits. The E
Series router signals this mapping to all routers on the tunnel. You can establish
different PHB-ID–to–EXP mappings for different tunnels.
PHB-ID–to–EXP mapping for the best-effort traffic class:
PHB-ID–to–EXP mapping for the af1 traffic class:
PHB-ID–to–EXP mapping for the af2 traffic class:
PHB-ID–to–EXP mapping for the ef traffic class:
Define classifier control lists to classify the incoming packets into classifier groups.
Although not shown here, for each CLACL you must define the rules that will select
the appropriate incoming packets: be, af1, af2, or ef.
