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

Predefined user roles
network-admin
Usage guidelines
The IPv6 fast forwarding feature will create fast forwarding entries for the device to speed up packet forwarding. When the traffic volume is high, the device will generate a large number of fast forwarding entries. These entries will cause high memory usage, which eventually leads to memory allocation failure for other services. In this case, you can disable this feature temporarily to free up device memory.
Do not disable IPv6 fast forwarding if the device runs session-based services. Disabling fast forwarding will make these services become ineffective:
· NAT.
· ASPF.
· Attack detection and prevention.
Examples
# Disable IPv6 fast forwarding.
<Sysname> system-view
[Sysname] undo ipv6 fast-forwarding enable
Related commands
display ipv6 fast-forwarding cache
reset ipv6 fast-forwarding cache
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.
Views
System view
Predefined user roles
network-admin
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 the IPv6 fast forwarding table.
Syntax
In standalone mode:
reset ipv6 fast-forwarding cache
In IRF mode:
reset ipv6 fast-forwarding cache [ slot slot-number ]
Views
User view
Predefined user roles

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. (IRF mode)
Examples
# Clear the IPv6 fast forwarding table.
<Sysname> reset ipv6 fast-forwarding cache
