Abstract: Some embodiments provide a network system. The network system includes a first set of host machines for hosting virtual machines that connect to each other through a logical network. The first set of host machines includes managed forwarding elements for forwarding data between the host machines. The network system includes a second set of host machines for hosting virtualized containers that operate as gateways for forwarding data between the virtual machines and an external network. At least one of the virtualized containers peers with at least one physical router in the external network in order to advertise addresses of the virtual machines to the physical router.

Abstract: Some embodiments provide a method for providing redundancy and fast convergence for modules operating in a network. The method configures modules to use a same anycast inner IP address, anycast MAC address, and to associate with a same anycast VTEP IP address. In some embodiments, the modules are operating in an active-active mode and all nodes running modules advertise the anycast VTEP IP addresses with equal local preference. In some embodiments, modules are operating in active-standby mode and the node running the active module advertises the anycast VTEP IP address with higher local preference.
