Configuring IPv6 fast forwarding

Overview

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.
•
VPN instance name.
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.

Commands and descriptions for distributed devices apply to MSR4060 and MSR4080 routers.
Configuring the aging time for IPv6 fast forwarding
entries
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.
To configure the aging time for IPv6 fast forwarding entries:
Step
1. Enter system view.
2. Set the aging time for IPv6
fast forwarding entries.

Remarks
N/A
By default, the aging time is 30 seconds.
