Abstract: A border leaf of a software defined computer network receives network traffic directed to a first endpoint from a second endpoint. The first endpoint is connected to the software defined network, and the second endpoint is external to the software defined network. If the border leaf determines that it does not have a stored network route for an active conversation between the first endpoint and the second endpoint, the border leaf determines a valid network route for the network traffic to reach the first endpoint. The border leaf stores the valid network route and forwards the network traffic to the first endpoint. The border leaf transmits a synchronization message to other border leaf nodes of the computer network. The synchronization message causes the other border leaf(s) to store the valid network route and an indication that the original border leaf is forwarding the network traffic in the active conversation.
