Exchange 2010 - DAG - Replication

Hey,

We have a three node DAG.  Two of the nodes are in one data center and one node in a secondary data center. Each node has one NIC configured for replication and on NIC for MAPI.

However, all replication traffic appears to be going across the MAPI connection.

The DAG appears to see the Replication network but does appear to be using it. Can someone guide me to blog or help me with some commands to verify this and force all replication across the replication network ?

Thanks,
Liam

When you setup the DAG, did you set the binding order of the NIC's?
To verify NIC binding order, open Network and Internet, go to Network connections
and click on Advanced (you will have to enable toolbar to see this option).
From there, click on advanced and the first tab is bindings, check to see which network is first and put the MAPI traffic on top if it isn't there already.

out of curiosity, what is your network setup like between the datacenters? Are they on the same subnet or different ones? You may be dealing with a dual gateway issue that is causing the replication network to lose communication with all the members. You must be able to communicate with each member of the replication network without interruption. If there is a gateway between the main site and second site, you will probably need to configure static routing on the Replication NICs to allow them to communicate without configuring a Default Gateway them. It's important to note that Windows Servers don't support dual gateways.

DagThank you all for your help, I have made some progress on this..

I now have 2 of the 3 server’s replicating correctly. The 2 servers in the same Data Center are replicating on the correct network. The remote node is not... This is the one I want to get working the most to reduce traffic on our MPLS network..

I noticed that the new Replication network was not showing up in the list of DAG networks. I manually added it, enabled replication and it added with the warning attached.  
I appear to have no network issues and can ping, trace route to all networks.

All help would be greatly appreciated.
Thanks
Liam

Please review the network requirements for DAG with multiple subnets.
