Abstract
Systems, methods, and computer-readable media for communicating policy changes in a Locator/ID Separation Protocol (LISP) based network deployment include receiving, at a first routing device, a first notification from a map server, the first notification indicating a change in a policy for LISP based communication between at least a first endpoint device and at least a second endpoint device, the first endpoint device being connected to a network fabric through the first routing device and the second endpoint device being connected to the network fabric through a second routing device. The first routing device forwards a second notification to the second routing device if one or more entries of a first map cache implemented by the first routing device are affected by the policy change, the second notification indicating a set of one or more endpoints connected to the second routing device that are affected by the policy change.
