The maximum load-balancing command sets the maximum number of equal-cost routes for load balancing. You need to set the maximum value according to memory capacity.
The undo maximum load-balancing command restores the default maximum number of equal-cost routes for load balancing.
By default, the maximum number of equal-cost routes on the S5720I-SI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730S-EI, S5730-SI, S6720S-SI, or S6720-SI is 8, and the maximum number of equal-cost routes on the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, or S6730S-S is 16.
| Parameter | Description | Value |
|---|---|---|
| number | Specifies the maximum number of equal-cost routes for load balancing. | The value is an integer that ranges from 1 to 8 on the S5720I-SI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730S-EI, S5730-SI, S6720S-SI, or S6720-SI. The value ranges from 1 to 16 on the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, or S6730S-S. |
If multiple routes are available on an IS-IS network, multiple equal-cost routes may exist. Use the load balancing method to allocate traffic evenly to each link. This method improves link efficiency on the network and reduces the congestion possibility caused by overloaded links.
Specify the number parameter to limit the number of equal-cost routes for load balancing.
PrecautionsTo cancel load balancing, set the number parameter to 1 or run the nexthop command to set the preferences of equal-cost routes.
