Abstract
Techniques are provided for two peer edge switches in an edge switch cluster of a first data center site to actively provide traffic flow redundancy in an active-active configuration and provide multi-homing support over an overlay transport virtualization (OTV) protocol. Information is stored indicating a media access control (MAC) address of at least one endpoint device at the first site. An edge switch in the edge switch cluster at the first site sends via an OTV protocol a Layer-3 message that is configured to advertise the MAC address of the at least one endpoint at the first site to enable at least one edge switch at a second site to perform multipath routing to the endpoint device at the first site based on each of the edge switches in the edge switch cluster at the first site.
