  We consider a one-dimensional Rashba nanowire in which multiple Andreev bound
states in the bulk of the nanowire form an Andreev band. We show that, under
certain circumstances, this trivial Andreev band can produce an apparent
closing and reopening signature of the bulk band gap in the non-local
conductance of the nanowire. Furthermore, we show that the existence of the
trivial bulk reopening signature (BRS) in non-local conductance is essentially
unaffected by the additional presence of trivial zero-bias peaks (ZBPs) in the
local conductance at either end of the nanowire. The simultaneous occurrence of
a trivial BRS and ZBPs mimics the basic features required to pass the so-called
"topological gap protocol". Our results therefore provide a topologically
trivial minimal model by which the applicability of this protocol can be
benchmarked.
