Question
Why we choose the router rather then L-3 Switch
 Question Submitted By :: Guest
I also faced this Question!!     Rank Answer Posted By  
 
  Re: Why we choose the router rather then L-3 Switch
Answer
# 1
because a router won't forward broadcasts and on a router 
you can create ACL and filter traffic

layer 3 switches are used for intervlan communication.they
will only break the broadcast in the vlan.but roters are
used to break broadcast in internetwork s.

Router is the software device it depend on the cpu power 
cycle but Switches are hardware device so the performance 
of the switches are much more faster than the router.

Answer
# 6
all have answered wrong,they have replyed about l2 switches
but the answer is not that
i donot know i am wright or not so plz mark if i am wrong 
or wright
now i am going to starting what is l3 switch
l-3 switch is that wich work on the l-3
wha does it mean.that mean that unlike l-2 switch l-3 
switch can understand ip address
 Layer 3 switching refers to a class of high-performance 
routers optimized for the campus LAN or
intranet, providing both wirespeed Ethernet routing and 
switching services
A Layer 3 switch router performs the following three major 
functions:
• Packet switching
• Route processing
• Intelligent network services
Compared to other routers, Layer 3 switch routers process 
more packets faster by using
application-specific integrated circuit (ASIC) hardware 
instead of microprocessor-based engines.
Layer 3 switch routers also improve network performance 
with two software functions—route
processing and intelligent network services.
then why we chose the router rather then l-3 switches.
so  answer is that l-3 switch act on fast ethernet as 
gigabyte ehternet,and another region is it having 
router+switches feature both which create broadcast strom 
per intrface,thus in the parctise swe choose router rather 
then l-3 switch
and cost have also matter.

i dont about L3 switch but i know about router 
router is work on layer 3 but it undrestand layer 4 too 
we are using router for path selection . packet 
forwording . connect to diffrent networks .and Security 
(Access-list) .
and main reson is router eazy to opearte then swithch .
