Abstract: In one embodiment, a method for improving routing for a stretched subnet includes receiving a first communication on a border leaf of the stretched subnet, where the border leaf is a top of rack (ToR) switch configured to facilitate connectivity between an internal data center fabric and at least one external site associated with the stretched subnet, based on routing information received with the received communication, identifying a source address for the received communication as either from within the internal data center fabric or from the at least one external site, and if the source address is from the external site, storing an abbreviated route based on the source address in at least one hardware table, where the abbreviated route is a route to the at least one external site, and upon subsequent receipt of a second communication to be forwarded to the source address, forwarding the second communication in accordance with the abbreviated route.

Abstract: Techniques are disclosed for configuring a LISP mobility network. A management tool receives a configuration for a network fabric. The configuration specifies values for one or more attributes associated with a Locator ID Separation Protocol (LISP)-enabled network. The management tool generates one or more commands based on the specified values for the one or more attributes associated with the LISP-enabled network. The generated commands are distributed to a plurality of network devices in the network fabric. Each network device executes the one or more commands to configure the network fabric.
