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.
