Junos MPLS Question

Hey guys, i’ve been studying for my JNCIS-SP and just got introduced to the deeper concepts of MPLS. There is one thing I can’t wrap my head around though.

Juniper devices have the inet.0 table for IP routes and the inet.3 for MPLS routes (or LSPs).

If the same destination IP is listed in both tables, how is it decided which “path” the traffic will actually take? Is it going to be routed or label switched to its destination?

Any clarification is much appreciated!
