Experts: I did some search the net trying to understand and resolve a confusion as how the the sequence of processing packets occur with MPLS traffic engineering. Below is a sample configutation and would like to understand how do the packets processesed and what is the sequencing of processing when they hit the destination.
———————————
interface Tunnel1
description COS0
ip unnumbered Loopback0
tunnel mode mpls traffic-eng
tunnel destination 1.2.3.4
tunnel mpls traffic-eng path-option 7 explicit name ABC
tunnel mpls traffic-eng path-option 15 dynamic
tunnel mpls traffic-eng exp 0 default
!
interface Tunnel2
description COS1-7
ip unnumbered Loopback0
tunnel mode mpls traffic-eng
tunnel destination 1.2.3.4
tunnel mpls traffic-eng path-option 7 explicit name DEF
tunnel mpls traffic-eng path-option 15 dynamic
tunnel mpls traffic-eng exp 1 2 3 4 5 6 7
!
interface Tunnel3
description MASTER
ip unnumbered Loopback0
tunnel mode mpls traffic-eng
tunnel destination 1.2.3.4
tunnel mpls traffic-eng exp-bundle master
tunnel mpls traffic-eng exp-bundle member Tunnel1
tunnel mpls traffic-eng exp-bundle member Tunnel2

Thanks for all the help !
