Hi all, people talk about layer 3 switching is best in the core, but what is the alternative, as it layer 3 means routing. does it mean that you should use a multilayer switch where the traffic is switched in hardware rather than cpu?
Every thing at layer 3 is essentially routing, routers usually do routing look-up in the memory and with CEF turned on they mimic the switching behavior of a multilayer switch whereas a switch will cache the routing table, entire or a part of it depending upon the resources available, to the hardware table (TCAM) and will work faster. You can have a multilayer switch at the core but routers have a lot of features that are not there in the switch, you may need those at any point in time.
