That's what I understood the first time, but thanks for trying to clarify
:-). I am saying that what I saw in the past was the repair continuing for
ranges not involving the dead node as you said, but all the failed ranges
will not be automatically resumed unless you use some external tool as
OpsCenter repair feature or Spotify Reaper (I believe both handle this by
putting to the queue all the ranges that fail to be re-run, I might be
wrong).

If a node is down in my cluster.

It is exactly what this ticket
https://issues.apache.org/jira/browse/CASSANDRA-10446 is about. Those
ranges including the dead node could be repaired between the 2 other
replicas that are up (considering RF=3). The work is to be done, you can
follow that, vote for it or even develop it if it is something that is
worth it for you Jean.
