Usage Guidelines

Usage Scenario

If the destinations and costs of the multiple routes discovered by one routing protocol are the same, load balancing can be implemented among those equal-cost routes. Link usage on a network can be improved and the network congestion caused by some heavily loaded links can be reduced. However, routes are randomly selected for forwarding traffic, which may be inconvenient for managing service traffic. The maximum load-balancing command sets the maximum number of equal-cost routes based on network settings to manage service traffic.

Prerequisites

Before running the maximum load-balancing command, run the isis command to create an IS-IS process.

Precautions

When the number of equal-cost routes on the networking is greater than that specified in the maximum load-balancing command, valid routes are randomly selected for load balancing.

Example

# Set the maximum number of equal-cost routes among which load balancing is performed to 2.
