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 six fields: source
IPv6 address, destination IPv6 address, source port number, destination port number, protocol number,
and VPN instance name. After the first packet of a flow is forwarded through the routing table, fast
forwarding creates an entry for the flow and uses the entry to forward subsequent packets of the flow.

Configuration procedure

To configure IPv6 fast forwarding:
Step
1. Enter system view.
2. Enable IPv6 fast forwarding.
3. Set the aging time of IPv6 fast
forwarding entries.

Displaying and maintaining IPv6 fast forwarding

Execute display commands in any view and reset commands in user view.
Task

By default, IPv6 fast forwarding is
enabled.
By default, the aging time of IPv6 fast
forwarding entries is 30 seconds.
