Abstract: Techniques and apparatus for allowing a network fabric to accept network devices associated with other fabric networks are described. An example technique involves establishing a communication session between a first network node and a first control plane of the network fabric, wherein the first network node supports a second control plane different from the first control plane; First routing information from the first network node is imported into a first routing table of the first control plane. Second routing information from a second network node is imported into a second routing table of the first network node.

Abstract: Techniques for automated configuration are provided. A first device detects a new device connected by one or more new links in a network, and the first device transmits, to a dynamic host configuration protocol (DHCP) server, a request for a first new subnet. The first device then assigns a first address of the first new subnet to a first new interface of the first device. The first device additionally transmits a second address of the first new subnet to the new device, where the new device uses the second address to establish connectivity to the network.

Abstract: In one embodiment, network node-to-node connectivity verification is performed in a network including data path processing of packets within a packet switching device. In one embodiment, an echo request connectivity test packet, emulating an echo request connectivity test packet received from a first connected network node, is inserted by the packet switching device prior in its data processing path prior to ingress processing performed for packets received from the first connected network node. A correspondingly received echo reply connectivity test packet is intercepted by the packet switching device during data path egress processing performed for packets to be forwarded to the first connected network node.
