Configuring Load Balancing on a LAG Link

You can configure the load balancing hash key for Layer 2 traffic to use fields in the Layer 3 and Layer 4 headers inside the frame payload for load-balancing purposes using the payload statement. You can configure the statement to look at layer-3 (and source-ip-only or destination-ip-only packet header fields) or layer-4 fields. You configure this statement at the [edit forwarding-options hash-key family multiservice] hierarchy level.

You can configure Layer 3 or Layer 4 options, or both. The source-ip-only or destination-ip-only options are mutually exclusive. The layer-3-only statement is not available on MX Series routers.

Note: For Dense Port Concentrators (DPC), any change in the hash key configuration requires a reboot for the changes to take effect. For Modular Port Concentrators (MPC) the reboot is not required.

For more information about link aggregation group (LAG) configuration, see the Junos® OS Network Interfaces.
