If the hashing is stable (which it is, if I understand the CLUSTERIP
feature of netfilter right) and thus one IP always connects to the same
cluster server, EAP should work as well.
And if one server goes down, EAP sessions in progress at that moment
will fail anyway and need to be restarted with a new target server, no
matter if one uses a classic primary/secondary setup or the clusterip
Sig lost. Core dumped.
