Configuring a Traffic Load Balancing Mode
Context
Routers support the multi-routed mode. That is, you can configure multiple routes with the same destination and preference. When multiple routes have the same destination and cost and are discovered by the same routing protocol, routers load balance traffic among these routes.
In network applications, routers often use load balancing to improve link efficiency and increase network bandwidth. 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.
The ip load-balance packet and ip load-balance hash commands cannot take effect simultaneously.
Procedure
- Configure UCMP and ECMP load balancing for traffic distribution.
- Configure per-packet load balancing for traffic distribution.
- Run ip load-balance packet
Traffic is distributed in per-packet load balancing mode.
By default, traffic is distributed in per-flow load balancing mode.
When packets need to be fragmented and the delay difference between two links is large, packet mis-sequencing may occur during packet reassembly if traffic is distributed in per-packet load balancing mode.
- Run ip load-balance packet
