In the above LAB topology I have 3 MPLS RSVP TE between the PEs( 1.1.1.1 and 8.8.8.8). I like to achieve -- Te 101 is for EXP 5, TE 102 for EXP4 and TE103 is for rest. But all traffic is passing through TE103. Did not able understand the actual cause of the problem, so need help. Thanks for your comments in advance.
Lab test was performed on XRV
