But in a pure layer 2 switch, to route between vlansyou will need an external router. In a layer 3 switch, routing can be donewithin the switch. Also, a layer 3 switch is probably going to give you QoSabilities like traffic marking and cvlassificagtion based on layer 3 andlayer 4 info in the packet.----- Original Message ----- From: "CCIE 2004" To: Sent: Tuesday, May 11, 2004 12:54 AMSubject: OT: Difference between Layer 2 and Layer 3 switches> Hi, I just wanted to get a brief overview of the general concept of layer2 and layer 3 switches. I did read a thread earlier on groupstudy and hadseen a recent article but cannot remember where I saw !
the article. I thinklayer 3 switches are mainly routers that are capable of caching and doing alookup on network layer addresses (ip, ipx etc) in Asic. Layer 2 switchesare mainly devices that build their table on source mac address. Is that agood enough explanation? Any additions or corrections to it would be great.Thank you>> _______________________________________________> Join Excite! - http://www.excite.com>; The most personalized portal on the Web!>> _______________________________________________________________________> Please help support GroupStudy by purchasing your study materials from:> http://shop.groupstudy.com>>; Subscription information may be found at:> http://www.groupstudy.com/list/CCIELab.html>;
