Usage Guidelines

Usage Scenario

In stable-preferred load splitting or balance-preferred load splitting mode, entries may not be well-balanced among paths because of the addition or deletion of entries, change of load splitting weights of the paths, or change of equal-cost routes. In such a case, the device will balance entries after a certain waiting time to reduce the impact of frequent changes on the system.

Currently, setting a load splitting timer to change the waiting time before balancing entries is supported.

If the network is stable, for example, when entries are not deleted or added frequently or equal-cost routes are not changed frequently, set the load splitting timer value to a smaller value so that entries can be balanced rapidly. The recommended value is 300 to 600 seconds.
If the network is not stable, for example, when entries are deleted or added frequently or equal-cost routes are changed frequently, set the load splitting timer value to a larger value to reduce the impact of frequent entry changes on the system and network stability. The recommended value is 1200 to 1800 seconds.

Prerequisites

IP multicast routing has been enabled using the multicast routing-enable command.
