ipv6 fast-forwarding load-sharing
Use ipv6 fast-forwarding load-sharing to enable IPv6 fast forwarding load sharing.
Use undo ipv6 fast-forwarding load-sharing to disable IPv6 fast forwarding load sharing.
Syntax
ipv6 fast-forwarding load-sharing
undo ipv6 fast-forwarding load-sharing
Default
IPv6 fast forwarding load sharing is enabled.

Usage guidelines
IPv6 fast forwarding load sharing enables the device to load share packets of the same flow. This feature identifies a data flow by using the packet information.
If IPv6 fast forwarding load sharing is disabled, 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.
<Sysname> system-Views
[Sysname] ipv6 fast-forwarding load-sharing
reset ipv6 fast-forwarding cache
Use reset ipv6 fast-forwarding cache to clear IPv6 fast forwarding entries.
