## Connecting With MultiSubnetFailover
Always specify `MultiSubnetFailover=True` when connecting to a SQL Server 2012 availability group listener or SQL Server 2012 Failover Cluster Instance. `MultiSubnetFailover` enables faster failover for all Availability Groups and or Failover Cluster Instance in SQL Server 2012 and will significantly reduce failover time for single and multi-subnet AlwaysOn topologies. During a multi-subnet failover, the client will attempt connections in parallel. During a subnet failover, will aggressively retry the TCP connection.
