I was trying to configure CEF on gns3. The above are tow screenshots of the lab.
From the debug output above we can see the ICMP packet is routed via FIB.
The FIB and adjacency tables are used by CEF to forward packets in hardware.
But the command sh int f0/0 | inc CEF shows ip cef is disabled. So how is the packet routed via FIB?
Can someone clarify for me??? thank you
