Abstract:
For a managed network implementing at least one logical router having centralized and distributed components, some embodiments provide a method that better supports the provision of certain network applications and/or services. The method receives at a host implementing (1) a distributed logical router and (2) a plurality of logical switches of a logical network along with other hosts, a message from a first data compute node (DCN) executing on the host. The host logically forwards the message to the distributed logical router that uses a particular anycast internet protocol (IP) address using a first media access control (MAC) address. The distributed router determines that the message requires processing by a centralized logical router (e.g., a service router, edge node, etc.) executing on an edge node host and forwards the message to the centralized logical router using the same anycast IP address and a second, unique MAC address.
