Configuring IPv6 fast forwarding
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 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.
Verifying and maintaining IPv6 fast forwarding
Verifying the aging time of IPv6 fast forwarding entries
To display the aging time of IPv6 fast forwarding entries, execute the following command in any view:
display ipv6 fast-forwarding aging-time
Displaying and clearing IPv6 fast forwarding entries
To display IPv6 fast forwarding entries, execute the following command in any view:
display ipv6 fast-forwarding cache [ ipv6-address ]
To clear IPv6 fast forwarding entries, execute the following command in user view:
reset ipv6 fast-forwarding cache
