Load Sharing
45.1 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.
