Hi nanog, When MPLS TE is partially deployed in an AS, in a given interface, there is coexistence between TE tunnel traffic, and normally per-hop routed traffic. Since the TE tunnel bandwidth was "booked" in advance via RSVP, I wonder if this part of TE bandwidth promise can be kept strictly by the router via build-in queuing mechanism when actually tunnel traffic comes in? Or on the contrary, the bandwidth reservation is only an planning step, no actual priority queuing protection on them against normal traffic ? If normal MPLS-TE didn't handle my question, will Cisco's new GB-TE(two pools) handle it ? Note, my question is different from the 8 preemption levels defined in MPLS-TE, the 8 preemption priority is used at the admission control phase, not when actual traffic comes in. thanks for any input.
