Abstract
A method forwarding data traffic based on a service chain policy for distributed gateway located within a network virtualization edge (NVE). The NVE may receive, within a first virtual overlay network, a data packet destined for a destination tenant end point located in a second virtual overlay network. The NVE may determine that a network service function is unavailable to treat the data packet between the first virtual overlay network and the second virtual overlay network. In order to route the data packet, the NVE may obtain a service chain policy that provides the location of a network node configured to treat the data packet with the network service function. The NVE may transmit the data packet toward the network node. A service chain policy may correspond to a sequence of network nodes that represents a path to the destination tenant end point.
