What happens if both both LSP_1 and LSP_2 want to be routed to prt_3?
Don't they get merged?

-> we do still have the possibility to maintain two separate LSPs at the
control plane level even if sharing of resource reservation occurs;
concerning the label it may or not be identical depending on whether the
explicit route for these LSPs is identical or not i.e. when path msgs have
different explicit route, separate LSPs must be established - note that the
inverse applies as well even if the explicit route are identical separate
labels can still be assigned
