What do you mean by "reestablish the link"? If you mean "reestablish the
network potential visibility of one node on the other one", then it is not
enough. You have to use net_adm:ping/1 (or in fact any function that makes
both nodes communicate) to have the nodes see (at the Erlang level) each other.
