Various systems and methods for performing fast fail-over. One method involves receiving a packet at a primary forwarder node of a core network, determining whether the packet was received from a secondary forwarder node of the core network, via a tunnel, and, in response to a determination that the packet was received via the tunnel, forwarding the packet to another node in the core network. The tunnel communicatively couples the primary forwarder node and the secondary forwarder node. The primary forwarder node and the secondary forwarder node communicatively couple a local network and the core network. The packet was transmitted from the local network.
