    Abstract: Disclosed herein are systems, methods, and computer-readable media for forwarding data in response to a detected local area network failure. In one aspect, a method includes identifying one or more EVPN services in a local area network. In one aspect, the method includes allocating one or more FRR labels, each of the FRR labels corresponding to each of the EVPN services. In one aspect, the method includes broadcasting the FRR labels to a plurality of network appliances of the LAN. In one aspect, the method includes determining one or more EVI-EAD routes associated with the FRR labels. In one aspect, the method includes detecting a LAN failure of one of the plurality of the network appliances. In one aspect, the method includes forwarding incoming data to another one of the plurality of the network appliances in accordance with the determined EVI-EAD routes, in response to detecting the LAN failure.

    Abstract: A method, network device, and computer program product for network traffic diversion are disclosed. In one embodiment, a method according to the present disclosure includes receiving a frame at a core edge node that is a member of a redundancy group (where the frame comprises network address information and a packet), and determining whether a link (to which the core edge node is communicatively coupled) is affected by a network failure. The frame was sourced by a remote core edge node that is not a member of the redundancy group, and the network address information indicates that the packet is to be forwarded via the link. In response to the link being affected by the network failure, the method further includes generating a modified frame and forwarding the modified frame to another core edge node. The generating comprises including a redirect label in the modified frame. The another core edge node is another member of the redundancy group.
