For routed packets:
The mac table is querried for the egress port of a packet. THis is the
switchng table/backplan switching engine
no egres port is found
an arp is initiated
No arp reply>
Routing engine routes the packet based on ip source and destinatin using
its routing table
The egress port is determined to be some port (gig 0/1)
The egress port is added to eh switching table.
all ramaining traffic from that flow is fast switched.
No routing is necessary.
I believe CEF works simurlarly.
