Abstract

Embodiments for handling multidestination traffic in a network are described. It is determined that a destination of a packet, received at a network device, is a multihomed destination. In response to determining that the destination of the packet is a multihomed destination, a hash value is determined from a selection of header values of the packet using a hash function. The packet is forwarded to the destination using a shadow hash forwarding table based at least in part on determining, based on the hash value and a hash forwarding table, that the network device is a designated forwarder for the packet.
