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.

Abstract: A method for identifying a first hop router (“FHR”) in a distributed virtualized network is presented. In an embodiment, a method comprises receiving a multicast message on an incoming interface. In response to receiving the multicast message, the router determines whether the router is a FHR for the multicast message, i.e., whether, in response to generating and transmitting a hello multicast message, the router does not receive a response on the incoming interface; or whether an interface to a RP for the multicast message is different than the incoming interface. If the router is the FHR for the multicast message, then the router determines an IP address of a RP for the multicast message. The router also encapsulates the multicast message into a unicast message, includes in the unicast message the IP address of the RP as a destination address, and transmits the unicast message to the RP.

Abstract: Embodiments described herein involve appliance migration. Embodiments include connecting, by a second appliance that is configured to perform a service, to a first uplink and a first downlink of a first appliance that is configured to perform the service. Embodiments include connecting, by the second appliance, to a first endpoint and a second endpoint to which the first appliance is connected. Embodiments include determining, by the second appliance, existing flows processed by the first appliance. Embodiments include processing, by the second appliance, a plurality of packets received via the first endpoint by: forwarding, by the second appliance, first packets of the plurality of packets that correspond to the existing flows to the first appliance; and performing, by the second appliance, the service for second packets of the plurality of packets that do not correspond to the existing flows.
