Abstract: This disclosure describes techniques for sharing routes between nodes in a distributed network system. An example method includes receiving, by a control node of a software-defined network (SDN) controller, a route from a compute node of a plurality of compute nodes in a network; publishing, by the control node and in response to receiving the route, a route update to an in-memory database service of the SDN controller; and sending, by the in-memory database service in response to receiving the published route update, the published route update to any of the plurality of compute nodes that have subscribed to receive route updates for an in-memory database instance associated with the control node.

Abstract: This disclosure describes techniques for improving route advertisements. In one example, a method includes generating, by a network device, a virtual private network address comprising a route distinguisher value and a network address associated with a compute node, the route distinguisher value based on a layer two physical hardware address of the compute node, and outputting, by the network device, a virtual private network route that includes the virtual private network address.

Abstract: Techniques are disclosed for seamless integration between a multicasting Virtual Private Network and an edge replicated multicast network. For example, a controller (e.g., software defined networking (SDN) controller) may facilitate the integration between a multicasting VPN network and an edge replicated multicast network through the selection of a multicast bridge node from virtual routers specified in the multicast replication tree, and sending information identifying the multicast bridge node to a provider edge (PE) device for the source VPN such that the PE device may use the information to steer multicast traffic from the source VPN site across the Layer 3 VPN network to the multicast bridge node of the receiver VPN site. When the multicast bridge node receives the multicast traffic, the multicast bridge node determines from the information that it is to receive the multicast traffic and to perform the edge replicated multicast using the edge replicated multicast tree.
