The one or more EVPN advertisements can be in an EVPN Network Layer Reachability Information (NLRI) advertisement, and the EVPN NLRI can have Route Type 1 for the information to apply to an EVPN Instance (EVI) and the EVPN NLRI can have Route Type 2 for the information to apply to a specific customer node based on a Media Access Control (MAC).

Abstract: A payment processing apparatus and a system or a method are provided that have a location-agnostic payment code, where the user does not have to check in to the merchant's location. Further, the reliance on the network connection is reduced by caching or storing payment codes at the user's mobile device. The payment codes may have expiration and may be used once. The payment codes may be revoked or canceled if the user's mobile device is compromised or stolen. In an embodiment, the payment codes may be generated and provided to the user's mobile device when the payment application at the user's mobile device is refreshed. For example, the payment application is refreshed based on user's payment history or payment habits. In another embodiment, the payment codes may be generated and provided to the user's mobile device when the user is within a predetermined distance from a merchant.

Abstract: Systems and methods for inducing a recovery of a service along a shorter path are provided. In one embodiment, a system having a processing device and a memory device is disclosed. The memory device is configured to store software logic including instruction that, when executed, enable the processing device to determine there is a defect in a primary Segment Routing (SR) to a main destination. The instructions further enable the processing device to identify an available path to an alternative destination that is shorter than a backup SR path to the main destination. Also, a main service associated with the main destination is switched over to an alternative service associated with the alternative destination based on the determining and the identifying.
