Abstract:
Various systems and methods for performing fast fail-over. For example, one method involves receiving a packet at a node. The packet is received at the node in response to a designated forwarder (DF) detecting loss of communication between the DF and a receiver node. The method also involves determining that the first packet was received via a tunnel. The method also involves forwarding the first packet and initiating a DF election. Forwarding the first packet and initiating the DF election are performed in response to determining that the first packet was received via the tunnel.
