Problems when I add the Second IP in DAG

I have the next DAG configuration

Site A and Site B are in differente subnet ( 10.57.57.x and 10.57.58.x )

Site A

MAPI NIC  Work fine

Replication NIC A  work fine

DAG IP is setup and the IP is avaliable in cluster resource


Site B

MAPI NIC  Work fine

Replication NIC work fine


Firewalls and Switchs are setups with free traffic for the two networks.


Site A and Site B are in remote sites.


I have two problems when I add the Second IP in DAG:


1) In Windows Failover Cluster the second IP of DAG, not view in the cluster resources.

   The "OR" dependency for the Network is not create because not is available the second IP.

   The failover not work with Site A is down.


2) The transport of logs from active to passive copy ( Site A --> Site B ) work but exist a high delay
   logs files in server with passive copy. The failover not work because
   log copy queue higher than the threshold of '40'.
