Setting the Maximum Number of Equal-Cost Routes

Setting the Maximum Number of Equal-Cost Routes


A CE12800 and CE12800E series switches supports load balancing among equal-cost routes. That is, you can configure multiple routes, which have the same destination and preference.


  1. Run system-view

    The system view is displayed.

  2. Run ospf [ process-id ]

    The OSPF process view is displayed.

  3. Run maximum load-balancing number

    The maximum number of equal-cost routes is set. The default value is 64.

    When the number of equal-cost routes is greater than the number specified in the maximum load-balancing command, OSPF selects valid routes for load balancing according to the following criteria:
    1. Route preference: Routes with higher preferences are selected for load balancing.
    2. Interface index: If routes have the same preference, routes with larger interface indexes are selected for load balancing.
    3. Next-hop IP address: If routes have the same preference and same interface index, routes with larger next-hop IP addresses are selected for load balancing.

  4. Run commit

    The configuration is committed.
