Hi,
I don't know if I understand you right. I assume you have two tunnels
(one explicit and one dynamic) between two PEs terminating on the same
IP addresses (perhaps loopbacks).
If so, by default all traffic will go thru the first tunnel which is
explicit path in your case.
If you want to specify what packets will go thru explicit tunnel and
what on the dynamic one, you need to differentiate somehow the
traffic. It is quite difficult because you have the same destination
addresses for both tunnels.
This can be done however using feature called MPLS DS-TE. It works
fine when you use 1 EXP value to direct traffic thru explicit tunnel
and rest of EXP will go thru dynamic tunnel..
Here's more info

I hope it helps.
