Abstract
Techniques are provided to prevent switches in a data center fabric path environment with fabric path extension devices from media access control (MAC) address flooding and MAC address table overflow. In such an environment, endpoints associated with virtual port channels are connected to multiple switches which normally would perform MAC address flooding across all switch forwarding engines. The switches in the fabric path exchange MAC synchronization messages based on source/destination specific connectivity such that MAC broadcast messages that advertise source/destination MAC addresses for endpoints do not have to be repeatedly sent and their corresponding MAC lookup tables do not have to be updated or include unnecessary MAC table entries.
