Abstract: A method is provided in one example embodiment and includes receiving a request to create a path through a network, wherein the path originates on a first network device and terminates on the second network device; identifying a first controller associated with the first network device, wherein the first controller proxies control plane functions for the first network device; identifying a second controller associated with the second network device, wherein the second controller proxies control plane functions for the second network device; and computing the path using the first controller as a source and the second controller as a destination. The first controller installs the computed path on the first network device and the second controller installs the computed path on the second network device.

Abstract: A method is provided in one example embodiment and includes configuring a local network element as an autonomic registrar for a designated network domain; establishing an autonomic control plane (“ACP”) between the local network element and one or more remote network elements identified by local network element as a remote neighbor; designating a locally-defined subnet at the local network element to be extended to each of the one or more remote network elements; and executing an ACP command at the local network element, wherein the executing triggers a message to each of the one or more remote network elements, the message including information regarding the designated local subnet. The information included in the message is used by each of the remote network elements to auto-resolve its Locator/Identifier Separation Protocol (“LISP”) configuration, enabling the designated local subnet to be extended to each of the one or more remote network elements.

Abstract: The present disclosure describes methods and systems for enabling a migration of network elements from a first location to a second location remote from the first location without changing the Internet Protocol (IP) addresses, subnet mask, and/or default gateway of the network elements. The first location has a first Locator/Identifier Separation Protocol (LISP) router configured on a stick and the second location having a second LISP router configured on a stick. Both the first LISP router and the second LISP router are on the same subnet. Effectively, LISP provides a Layer 3 extension stretching a subnet across the first location and the second location (Stretched Subnet Mode (SSM)). By implementing LISP routers in this manner, system engineers can migrate network elements easily between two locations.
