Configuring load sharing

Overview

If a routing protocol finds multiple equal-cost best routes to the same destination, the device forwards
packets over the equal-cost routes to implement load sharing.
Configuring load sharing
Per-flow load sharing allows the device to forward flows over equal-cost routes. Packets of one flow travel
along the same routes. You can configure the device to identify a flow based on the source IP address,
destination IP address, source port number, destination port number, IP protocol number, and ingress
port.
In a complex network, when these criteria cannot distinguish flows, you can use the algorithm keyword
to specify an algorithm to identify flows for load sharing.
To configure per-flow load sharing:
Step
1. Enter system view.
2. Configure per-flow load
sharing.

Enabling local-first load sharing

This feature is available in Release 2406P03 and later versions.
Use local-first load sharing in an IRF fabric to distribute traffic preferentially across member ports on the
receiving device.
To enable local-first load sharing:
Step
1. Enter system view.
2. Enable local-first load
sharing.

Remarks
N/A
By default, the device performs
per-flow load sharing based on the
following criteria: source IP
address, destination IP address,
source port number, destination
port number, IP protocol number,
ingress port, and VLAN.
The ingress-port keyword is
available in Release 2406P03 and
later versions.
Remarks
N/A
By default, local-first load sharing
is enabled.
