Load balancing is classified as equal-cost multiple path (ECMP) or unequal-cost multiple path (UCMP). ECMP is automatically implemented by routing protocols, with no need for manual configuration, whereas UCMP is implemented using commands.

Load Balancing Classification

Based on the load balancing traffic among different links, load balancing is classified into two types:
  • ECMP evenly load-balances traffic over multiple equal-cost paths to a destination, irrespective of bandwidth. Equal-cost paths have the same cost to the destination.

  • UCMP load-balances traffic over multiple equal-cost paths to a destination based on bandwidth ratios. All paths carry traffic based on their bandwidth ratios.
