Configuring load sharing

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.

Command and hardware compatibility

Commands and descriptions for centralized devices apply to the following routers:
•
MSR1002-4/1003-8S.
•
MSR2003.
•
MSR2004-24/2004-48.
•
MSR3012/3024/3044/3064.
•
MSR954(JH296A/JH297A/JH298A/JH299A/JH373A).
•
MSR958(JH300A/JH301A).
Commands and descriptions for distributed devices apply to MSR4060 and MSR4080 routers.

Configuring per-packet or per-flow load sharing

Load sharing can be implemented in one of the following ways:
•
Per-packet—The device forwards packets over equal-cost routes.
•
Per-flow—The device forwards 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 following criteria:
source IP address, destination IP address, source port number, destination port number, IP
protocol number, and ingress port.
In a complex network, when the five tuples cannot distinguish flows, you can use the algorithm
keyword to specify an algorithm to identify flows.
To configure per-flow or per-packet load sharing:
Step
1. Enter system view.
2. Configure load sharing.
Command
system-view
•
Centralized devices in standalone mode:
ip load-sharing mode per-flow
[ dest-ip | dest-port | ip-pro | src-ip |
src-port ] * global
•
Distributed devices in standalone
mode/centralized devices in IRF mode:
ip load-sharing mode per-flow
[ dest-ip | dest-port | ip-pro | src-ip |
src-port ] * { global | slot slot-number }
•
Distributed devices in IRF mode:
ip load-sharing mode per-flow
[ dest-ip | dest-port | ip-pro | src-ip |
src-port ] * { chassis chassis-number
slot slot-number | global }

Remarks
N/A
By default, the device
does not perform load
sharing.
