MPLS DS-TE how the traffic is mapping with a CT?

[heiliger-eliet]

hi there ! 

Reading about MPLS TE Diffserv-Aware (DS-TE) IETF Mode, I have doubts about how the BC models direct traffic through a specific tunnel.Do I have to use MPLS TE Class-Based Tunnel Selection (CBTS) to steer traffic according exp field mapped to  ct?

Rsvp use to draw path from one end to other' the class-type you config in one end is send with rsvp through path' inform the other routers how to select correct path according to affinity of link

So! for example if I configure a network to work with RDM or MAM model , Ill configure tunnel with a specific class(BCn) and to use a specific tunnel for a specific kind of traffic I can use CBTS?
