In the case of Transalpine Gaul, Julius Caesar
finally had enough of the high country tribes
and subjugated them along with all of Gaul.

In earlier yrs the tribes of alpine Gaul would head
south and harrass Roman interests on and near
the coast of the Mediterranean.
this schitt eventually came to a head in 102 BC,
when Gen. Gaius Marius (Battle of Aquae Sextiae)
defeated the tribes, which included Germanics.

Roman Hispania you can see was largely annexed
by the time of Augustus...
The Iberian peninsula came into Roman hands
after the defeat of Carthage some two centuries
earlier , and gradually Rome pretty much subdued
and pacified all the tribes .. that pocket to the north
held out the longest, not necessarily coz they were
the toughest, but in part coz they didn't pose too much
of a problem to Roman interests in Hispania... but they
too were eventually dealt with and absorbed.
