Configuring a Load Balancing Mode for IP Packet Forwarding

Context

If flow-based load balancing is used, the hash algorithm is used to calculate a value for selecting a link to forward packets. The value is calculated based on the protocol type, source IP address, destination IP address, source port number, and destination port number.

If packet-based load balancing is used, packets are forwarded through different links. Packet-based load balancing can be implemented only for packets forwarded by the CPU such as protocol packets.

Procedure

Run system-view
The system view is displayed.
Run load-balance { flow | packet } [ all | slot slot-id ]
The flow-based load balancing mode is configured for IP packet forwarding.

By default, flow-based load balancing is used.

The load-balance command can also be used for MPLS packets.
