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 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:
|
