Abstract
A PIM vLAG network load balancing system includes a first vLAG switch and a second vLAG switch each connected to, and receive data traffic from, an upstream network device. The first and second vLAG switches balance network data traffic by both determining a source IP address and a multicast group address associated with the received data traffic, hashing the addresses, combining the hashed addresses to determine a resultant value, and either dropping or transmitting the received data traffic to a downstream network device based upon the resultant value. The first vLAG switch may transmit and the second vLAG switch may drop the received data traffic if the resultant value is a first binary value. The second vLAG switch may transmit and the first vLAG switch may drop the received data traffic if the resultant value is a second binary value.
