Abstract:
1. In a first node of a physical network supporting multiple virtual network connections, a method to dynamically modify configuration data supporting virtual networks, the method comprising: receiving i) destination network address information associated with at least one host computer, and ii) a corresponding gateway identifier of a gateway in the physical network, the gateway being an ingress edge node of the physical network through which the at least one host computer communicates; generating a notification message including the destination network address information and the corresponding gateway identifier; and transmitting the notification message to a second node of the physical network enabling the second node to create a mapping between the at least one host computer and a virtual network connection between the second node and the first node on which to forward data messages from the second node through the gateway to the at least one host computer based on identifying, as specified by the mapping, that the data messages having the destination network address information are to be mapped to and sent over the virtual network connection to the at least one host computer through the gateway as specified by the corresponding gateway identifier.
