Usage Guidelines

Applicable Environment

If a routing protocol discovers multiple routes with the same cost to a single destination, they can carry out load balancing. The maximum load-balancing command sets the maximum number of equal-cost routes that can carry out load balancing. This optimizes the routing policy and ensures traffic forwarding on a complex network.

Effect

Packets will be load-balanced by multiple equal-cost routes to a single destination.

Follow-up Procedure

If more existing equal-cost OSPFv3 routes than the value set using the maximum load-balancing command are available, the system randomly selects equal-cost routes equal to the value set using this command to carry out load balancing. The nexthop command allows routes with a specified weight to carry out load balancing.

Precautions

To disable load balancing, set the value of number to 1.

Example

# Set the maximum number of equal-cost routes that OSPFv3 can support to 3.

<HUAWEI> system-view
[~HUAWEI] ospfv3 1
[*HUAWEI-ospfv3-1] maximum load-balancing 3

# Restore the default maximum number of equal-cost routes for carrying out load balancing.

<HUAWEI> system-view
[~HUAWEI] ospfv3 1
[*HUAWEI-ospfv3-1] undo maximum load-balancing
