Does anybody have some usefull links or information regarding CEF/Multi-layer switching? How are these features interacting with each other? Key differences?
Basically in MLS the first packet to reach the destination rill need to be processed by router as it just maintain the caches and so for second packet it gets wr writed in hardware.
But in CEF even the first packet is hardware switches as it builds the adjacency table and FIB table. Which not only maintains the routing entried but also the arp entried like binding the mac with ip so that even first packet can be hardware switches.
