  • Patent number: 11888735
    Abstract: In some embodiments, a method for selecting an egress point for accessing an external network associated with a distributed logical router that is distributed across at least a first computing device and a second computing device is provided. The method receives, by an instance of the logical router at the first computing device, first identification information and a first preference value. The method compares the first preference value to a second preference value. The second preference value is associated with second identification information corresponding to a current computing device that is identified as a current preferred egress point for the logical router. The method determines whether to set the egress point connected to the instance of the logical router in the second computing device as a new preferred egress point for the logical router.

  • Patent number: 11876675
    Abstract: Some embodiments provide a method of migrating a first software defined (SD) network managed by a first network manager to a second SD network managed by a second network manager. The method of some embodiments is performed by a third network manager that provides an interface that allows a set of users to specify and review logical network components, which the first and second network managers can then respectively deploy in the first and second SD networks. The third network manager in some embodiments identifies for a migration manager a first group of two or more logical network components that the third network manager previously specified for the first network manager to deploy in the first SD network.

  • Publication number: 20220360530
    Abstract: Some embodiments provide a method for a network controller operating on a host machine that hosts a particular one of multiple centralized routing components for a logical router. The method receives a routing table from a routing protocol application operating on the host machine. Each of the other centralized routing components operates on a different host machine and implements a different interface of the logical router that connects to at least one physical router external to the logical network. The routing protocol application operates as a router server for all of the centralized routing components. For each of the other centralized routing components, the method identifies a set of routes in the routing table to distribute to the centralized routing component. The method sends the identified routes for each centralized routing component to the centralized routing component.

  • Patent number: 11431635
    Abstract: Some embodiments provide a method for a host computer that executes a set of data compute nodes (DCNs), for identifying a designated router for a multicast group. The method receives a membership request message to join the multicast group from a particular DCN of the set of DCNs, the membership request message including an address associated with the multicast group. The method identifies a logical router gateway from a set of logical router gateways as the designated router for the multicast group, based at least in part on the address associated with the multicast group, where different logical router gateways from the set of logical router gateways are assigned as designated routers for different multicast groups with different associated addresses. The method forwards the membership request message to the identified logical router gateway.

  • Patent number: 11336556
    Abstract: Some embodiments provide a method for a first edge device in a first datacenter that implements a centralized routing component of a logical router that spans multiple datacenters and handles data traffic between a logical network implemented across the multiple datacenters and external networks. From a second edge device in a second datacenter, the method receives via routing protocol a route having a particular routing protocol tag. When the first datacenter is a primary datacenter for the logical router such that all data traffic between the logical network and the external networks is handled by one or more centralized routing components implemented at the first datacenter, the method uses the routing protocol tag to determine whether to advertise the received route to the external networks.

  • Patent number: 11283637
    Abstract: The technology disclosed herein enables multicast network traffic to pass an RPF check in a logical router having separated packet handlers. In a particular embodiment, a method includes, in a north/south packet handler of a first logical router, receiving first network traffic from an east/west packet handler of the logical router. The first network traffic is multicast network traffic and the logical router is a first hop router for the first network traffic from a source of the first network traffic. The method further includes identifying an entry for the source in unicast routing information for unicast network traffic. Identifying the entry indicates that the first network traffic passes a reverse path forwarding (RPF) check. In response to the first network traffic passing the RPF check, the method includes transferring the first network traffic from the north/south packet handler to a next hop for the first network traffic indicated by first multicast routing information.

  • Patent number: 11153122
    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.
