Auto-discovery and provisioning of IP fabric underlay networks for data centers

Abstract:

Techniques are described for automatic discovery and provisioning of an IP fabric underlay network for use by an overlay network of a data center. The techniques provide mechanisms for management of the IP fabric underlay network, particularly as network devices are added to the underlay network topology for use by the overlay network. The techniques enable a control plane of a network device in the IP fabric underlay network to monitor discovery of neighbor network devices and link local addresses for the neighbor network devices. The disclosed techniques further enable a control plane of the network device to configure routing sessions between the network device and each of the discovered neighbor network devices based on the link local addresses for the neighbor network devices. The configuration of the routing sessions may include an exchange of loopback addresses for the network devices used by the overlay network.
