Consider a network with MPLS enabled routers as shown in Figure 1 below. We would like to perform traffic engineering using MPLS so that traffic from R1 to R6 will be routed as R1->R3-R5->R6->A and traffic from R2 to R6 will be routed as R2->R3->R4->C. Port 0 or R1 R4 Port 1 Port 0 Port 0 Port R3 R6 Port 0 ort 0 R2 R5 Figure 1. MPLS enabled network for Problem 1 Please fill in the following tables of MPLS entries for each router R1 Dst In label Out label Out interface 0 R2 In Labe Label Out Dst Out interface
