Abstract: A method is described and in one embodiment includes identifying at an initiator element a list of Internet protocol (“IP”) prefixes corresponding to routes designated as interesting routes, wherein the IP prefixes are included in a Routing Information Base (“RIB”) of the initiator; monitoring the RIB for a change in the list of IP prefixes; and, responsive to detection of a change in the list of IP prefixes, injecting at least a portion of the changed list of IP prefixes into a payload of an IKEv2 NOTIFY message and sending the IKEv2 NOTIFY message to a responder element peered with the initiator element, wherein the responder element updates an RIB of the responder element using the IP prefixes included in the received IKEv2 NOTIFY message.

Abstract: Techniques are providing for managing and optimizing the configuration of network devices. At a management device in a network, a message is received from a first network device via a wireless link or a power line communication link between the management device and the first network device. The new network device is classified as belonging to one of a plurality of network device zones based on evaluating the message. A response message is then sent to the new network device via the wireless link or the power line communication link to ensure secure access to a virtual console-port is provided for the management device and the network devices in the network device zones.

Abstract: A management device for a low power wide area network can: generate and send, to each constrained wireless network device via a wired gateway, a link layer multicast listener command specifying a listening interval and causing each constrained wireless network device to change from a low-power optimized mode to a listening mode until reception of a multicast data packet within the listening interval; generate collision avoidance parameters including a minimum waiting interval, a maximum waiting interval relative to the listening interval, and a redundancy constant; and instruct the wired gateways to selectively transmit the multicast data packet based on the collision avoidance parameters, wherein each wired gateway responds by waiting a randomly-selected wait interval between the minimum and maximum waiting intervals, and selectively transmitting the multicast data packet only if a received number of the multicast data packet by the corresponding wired gateway is less than the redundancy constant.
