correct. it would take whatever best paths it finds in the
inet table

the metric of the rsvp LSP will take the igp metric per
default so if the paths to the same destination have
different paths you may get a different metric for the
two LSP's as well. In case both LSP's have the same metric
you can set the metric on the labelswitch-path as well.
