What happens to EID values when the network topology is disabled and then re-enabled — are they regenerated or preserved?

I assume they are regenerated but just want to confirm.

A bit of an assumption on my part - EID is OID?
The global ID and OID are both retained when Topology is disabled and then reenabled. 
The disabling and reenabling marks all subnetworks as dirty but I don't think it changes any of the identifiers.
