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 !
