Usage guidelines
This feature enables the device to load share packets of the same flow. This feature identifies a data flow by using the packet information.
If this feature is disabled on the software side, the device identifies a data flow by the packet information and the input interface. No load sharing is implemented.
Examples
# Enable IPv6 fast forwarding load sharing on the software side.
<Sysname> system-Views
[Sysname] ipv6 fast-forwarding load-sharing
reset ipv6 fast-forwarding cache
Use reset ipv6 fast-forwarding cache to clear the IPv6 fast forwarding table.

Parameters
slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command clears the IPv6 fast forwarding table for all member devices.
Examples
# Clear the IPv6 fast forwarding table.
<Sysname> reset ipv6 fast-forwarding cache
