  The aim of this note is to study octahedrality in vector valued
Lipschitz-free Banach spaces on a metric space under topological hypotheses on
it. As a consequence, we get that the space of Lipschitz functions on a metric
space valued in a dual Banach space satisfies the weak-star strong diameter two
property, under natural topological hipothesess on the metric space. Also, we
show an example proving that these hypotheses are optimal.
