CHAPTER 43
Load Sharing
43.1 Load Sharing Overview
The Switch learns the next-hop(s) using ARP and determines routing path(s) for a
destination. The Switch supports Equal-Cost MultiPath (ECMP) to forward packets
destined to the same device (A for example) through different routing paths (1, 2
and 3) of equal path cost. This allows you to balance or share traffic loads
between multiple routing paths when the Switch is connected to more than one
next-hop. ECMP works with static routes or a routing protocol, such as OSPF.
With ECMP, packets are routed through the paths of equal cost according to the
hash algorithm output.
