How to Implement Load Balancing in a Scenario with Two Egress Devices

How to Implement Load Balancing in a Scenario with Two Egress Devices

Procedure

In a scenario with two egress devices, you can configure two equal-cost default routes to implement load balancing and configure load balancing based on the source IP address to load traffic of different users among different equal-cost routes.

Configure load balancing in a scenario with two egress devices.
<Huawei> system-view
[Huawei] sysname RouterA
[RouterA] ip route-static 0.0.0.0 0 GigabitEthernet1/0/0 
[RouterA] ip route-static 0.0.0.0 0 GigabitEthernet2/0/0 
[RouterA] ip load-balance hash src-ip

More Information

Equal-cost routes have the same route preference and metric and can implement load balancing.

During load balancing, by default, packets with the same source and destination IP addresses are forwarded using the same route and packets with different source and destination IP addresses are forwarded using different equal-cost routes. In real-world applications, to utilize link resources, different methods need to be used to forward packets. You can flexibly configure load balancing modes to meet different scenario requirements. Currently, AR routers support the following load balancing modes:
  • Load balancing based on the source IP address.

  • Load balancing based on the destination IP address.

  • Load balancing based on the source and destination IP addresses.
