You will see both NICs, one will be for MAPI traffic and the other will be for Replication traffic. That is by design.

OK, but will it first try to use 'ReplicationDagNetwork01' ? Both networks are replication enabled so how is the choice being made ?

Exchange 2013 dag confusion<br />
<br />
I created DAG in my new Exchange 2013 organisation.<br />
Prior to adding members, I configured a second NIC on each server following various guides.<br />
I only gave it IP and subnet mask, it's a different subnet than client access NIC, i changed the order so the CLIENT NIC is above REPL NIC, I unticked register....DNS and checked Disable NetBIOS.<br />
<br />
I expected that the DAG wizard will pickup the network I intended for replication only, but after creating a DAG, I see 2 networks in the DAG network section in ECP.<br />
<br />
They are named MapiDagNetwork and ReplicationDagNetwork01.<br />
<br />
Is that by design ? Should I see these 2 networks or should it be only the one I configured for replication ?<br />
<br />
Thanks
