Hi Acee, Let me clarify what I meant.
The DR will use the Link-LSAs to produce the intra-area-prefix-LSA for the transit networks. However, as long as we omit the global address from the intra-area-prefix-LSA, the global address won't be installed in the routing table, no matter if the global address has been advertised in the Link-LSAs or not. In other words, for prefix-hiding, we don't need to omit the global address in the Link-LSAs.
