Abstract:
For a set of gateway devices at the edge of a logical network, some embodiments provide a method for ensuring that data messages from an external network requiring a stateful service are received at an active gateway device. The method advertises the availability of a set of internet protocol (IP) addresses from standby gateway devices with a higher cost than the cost advertised by an active gateway device. In some embodiments, the advertisement is made using a border gateway protocol. Data messages may be unexpectedly received on a standby node despite the higher advertised cost. This could happen due to asymmetric network failures. The method determines if a stateful service is needed for the data messages received on standby node. Based on the determination, the method forwards the received data message to the active gateway device for the active gateway device to provide the stateful service.

Claim (Index 5):
The method of  claim 1 , wherein determining that the received data message requires the stateful service is based on a policy based routing entry specifying at least one of a destination IP address, range of IP addresses, source media access control (MAC) address, source port, destination port, and protocol as criteria for requiring the stateful service.
