(if you are multi-homed, just pick one) If the system has multiple addresses, its clients may not know all of them and may fail to detect loops. Addresses are no good. We need each server (or rather the clock) to have an ID and extend the protocol to exchange this ID so clients (that operate also as servers) can reliably detect 1-degree loops. The suggested-refid EF basically does that. -- Miroslav Lichvar
