Abstract: A network device identifies an Open Shortest Path First (OSPF) link between the network device and a layer 2 network as one of a point-to-multipoint over broadcast interface or a point-to-multipoint over non-broadcast multi access (NBMA) interface, and performs database synchronization and neighbor discovery and maintenance using one of a broadcast model or a NBMA model. The network device also generates a link-state advertisement for the network device, where the link-state advertisement includes a separate link description for each point-to-point link within the layer 2 network; and sends the link-state advertisement to each fully adjacent neighbor in the layer 2 network.

Abstract: In some embodiments, an apparatus includes a network node operatively coupled within a network. The network node is configured to send a first authentication message upon boot up, and receive, in response to the first authentication message, a second authentication message configured to be used to authenticate the network node. The network node is configured to send a first discovery message, and receive, based on the first discovery message, a second discovery message configured to be used by the network node to identify an address of the network node and an address of a core network node within the network. The network node is configured to set up a control-plane tunnel to the core network node based on the address of the network node and the address for the core network node and receive configuration information from the core network node through the control-plane tunnel.

Abstract: Techniques are described for implementing one or more logical routers within a single physical routing device. These logical routers, as referred to herein, are logically isolated in the sense that they achieve operational and organizational isolation within the routing device without requiring the use of additional or redundant hardware, e.g., additional hardware-based routing controllers. The routing device may, for example, include a computing platform, and a plurality of software process executing within the computing platform, wherein the software processes operate as logical routers. The routing device may include a forwarding component shared by the logical routers to forward network packets received from a network in accordance with the forwarding tables.

Abstract: In some examples, a controller comprises one or more processors; a control unit configured to obtain, from a router in a first network, a route that specifies a next hop to an address prefix reachable by the first network; and a service chain unit configured to generate a modified route that specifies a service node as the next hop for the address prefix, wherein the service node is external to the first network, and wherein the control unit is further configured to send the modified route to a second network, the modified route marked with an import route target configured for a provider edge router of the second network so that traffic from the first network and destined for the second network is forwarded to the service node.
