L3 sw Vs multilayer sw???? CBT nug. says they are different?
Morning all,
One more thing .... I have went through CBT nugget for BCMSN.... They says there that there is a difference between L3 switch and a multilayer switch!!! because a L3 switch is a switch with a router, while multilayer switch is a having CEF to cache from its router. Is that True ? This totally new to me ?
One more thing.... Can i use L3 switches (e.g. 3560) instead of routers for studying BSCI? [/code]

A multilayer switch can make forwarding decisions based on layers 2-7. L4-7 switching or sometimes called content switching can also be done. This is used to switch traffic based on application, port number etc. A L3 switch is still a multilayer switch as it switches on multilayers (2 & 3).
If you use 3560 swithces for BSCI you will not be able to do WAN links such as frame relay because you will not have serial interfaces.An expert is a man who has made all the mistakes which can be made. -

That's right. Multilayer switches do deeper packer inspection so you can get switched based on layer 4 ports, session-IDs, URLs etc. Content switches like CSS11000 etc to name just one work like this.
