Abstract
A method including determining that network traffic being transmitted is unicast or multicast; mapping to which virtual network and locator address each host belongs; generating leaking data for unicast and multicast traffic, wherein the leaking data indicates that a first virtual network leaks traffic to a second virtual network; receiving a request from the second virtual network to receive traffic from a host in the first virtual network; determining, based on the leaking data and the type of traffic being transmitted, if the first virtual network leaks traffic to the second virtual network; if the first virtual network leaks traffic to the second virtual network, determining a locator address for the host in the first virtual network using the mapping data; and transmitting the locator address for the host to the second virtual network to enable traffic leaking from the host to the second virtual network is disclosed.
