Abstract: Techniques for network routing border convergence are described. Backup paths for external connections for a network are established and provide for a temporary path for network traffic during network routing convergence, preventing traffic loss at network border nodes.

Abstract: In one embodiment, a method generally includes a first edge (E) node in a network receiving an encapsulated data packet, wherein the encapsulated data packet comprises an outer header and a data packet, wherein the outer header comprises a first router locator (RLOC) corresponding to the first E node, wherein the data packet comprises an internet protocol (IP) header, and wherein the IP header comprises a destination endpoint identification (EID) corresponding to a host H. The first E node determines whether the host H is attached to the first E node. And in response to the first E node determining the host is attached to the first E node, the first E node forwards the data packet to the host H. The first E node receives a message from another node after the host H detaches from the first E node and reattaches to another E node, wherein the message comprises the destination EID.

Abstract: Embodiments herein describe pruning a neighbor list sent to a client device using a predefined assignment corresponding to an AP or the client device which can reduce the time required for the client device to roam between APs in a WLAN deployment. The pruned neighbor list serves as a Wi-Fi client steering mechanism to affect which AP the client device chooses when roaming. In one embodiment, a controller uses information regarding fabric nodes in the backend infrastructure to prune the neighbor list to include only the APs that are assigned to the same fabric node as the current AP. In another embodiment, the controller considers a service provider corresponding to the client device when pruning the neighbor lists. The list may include only the neighboring APs assigned to provide Wi-Fi access for the same service provider.
