About IPv6 fast forwarding
Fast forwarding reduces route lookup time and improves packet forwarding efficiency by using a high-speed cache and data-flow-based technology. It identifies a data flow by using the following fields:
· Source IPv6 address.
· Destination IPv6 address.
· Source port number.
· Destination port number.
· Protocol number.
After a flow's first packet is forwarded through the routing table, fast forwarding creates an entry and uses the entry to forward subsequent packets of the flow.

Configuring IPv6 fast forwarding
About this task
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.
Procedure
1. Enter system view.
system-view
2. Configure IPv6 fast forwarding.
¡ Enable IPv6 fast forwarding.
ipv6 fast-forwarding enable
¡ Disable IPv6 fast forwarding.
undo ipv6 fast-forwarding enable
By default, IPv6 fast forwarding is enabled.
Configuring the aging time for IPv6 fast forwarding entries
About this task
The IPv6 fast forwarding table uses an aging timer for each forwarding entry. If an entry is not updated before the timer expires, the device deletes the entry. If an entry has a hit within the aging time, the aging timer restarts.
Procedure
1. Enter system view.
system-view
2. Set the aging time for IPv6 fast forwarding entries.
ipv6 fast-forwarding aging-time aging-time
By default, the aging time is 30 seconds.
Configuring IPv6 fast forwarding load sharing
About this task
IPv6 fast forwarding load sharing enables the device to identify 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.
Procedure
1. Enter system view.
system-view
2. Configure IPv6 fast forwarding load sharing. Choose one option as needed:
¡ Enable IPv6 fast forwarding load sharing.
Ipv6 fast-forwarding load-sharing
¡ Disable IPv6 fast forwarding load sharing.
undo ipv6 fast-forwarding load-sharing
By default, IPv6 fast forwarding load sharing is enabled.
