820 CHAPTER 55: IP ROUTING O VERVIEWprotocol has its own route redistribution mechanism. For detailed information,refer to “Routing Policy Configuration” on page 991.Configuring LoadSharingLoad sharing is implemented in the following ways:■ Flow-based load sharing: After enabled with fast forwarding, a device can onlyperform flow-based load sharing. For example, assume there are twoequal-cost routes on the device. If one data flow is to pass through the device,it will be forwarded through either route; if two data flows are to pass through,they will be forwarded through the two routes separately.■ Packet-based load sharing: With fast forwarding disabled, the device canevenly forward packets over the two equal-cost routes.■ Bandwidth-based non-balanced load sharing: With fast forwarding disabled,the device can forward packets based on the configurable bandwidths of theinterfaces. The greater bandwidth an interface has, the more packets itforwards.ConfiguringBandwidth-basedNon-Balanced LoadSharingFollow these steps to enable bandwidth-based non-balanced load sharingn Bandwidth-based non-balanced load sharing does not support the load sharing offlows. Therefore, you have to disable fast forwarding on the correspondingoutbound and inbound interfaces.Configuring the LoadSharing Bandwidth foran InterfaceFollow these steps to configure interface load sharing bandwidth:n ■ The load sharing bandwidth of an interface defaults to the physical bandwidthof the interface.■ If you specify a value of 0 for the bandwidth argument, routing is disabled onthe interface and the interface will not be used for load sharing. But this doesnot affect other states of the physical interface.To do... Use the command...
