Question
hi friends i am jitendera kumar sinha.i have a question in
mind that what is the diffrence between router and l3 switch
i serched on google and found that switch L3 is best in lan
and router are best in wan and switch are more faster then
router.beside that any short of technical diffrence if you
body know then plz plz and plz reply.
my 2nd question is that why we canot replace router with L3
switches (donot tell that it is costly then router).i want
any technical cause.
this is 1 am hope in noon when ever i logg again i will find
the answer posted by you.

thanks onse again
plz pzl make reply
thanks

Answer
# 1
Layer 3 switch do routing with Aisc chips router do with
microprocessor and its associated software
Router can be used to join different networks.L3 switch
cann't join different network.
Router needed especially where connections to the wide area
are required.
Router support many routing protocols.L3 bswitch support
very few routing protocol.

Hi, I m Shahin Ahmed. I also don't have much knowledge on
that. Still trying to explain it. Hope it'll help you.

Layer 3 switch is a high-performance device for network
routing. Layer 3 switches actually differ very little from
routers. A Layer 3 switch can support the same routing
protocols as network routers do. Both inspect incoming
packets and make dynamic routing decisions based on the
source and destination addresses inside. 


The key difference between Layer 3 switches and routers lies
in the hardware technology used to build. The hardware
inside a Layer 3 switch combine that of traditional switches
and routers, replacing some of a router's software logic
with hardware to offer better performance in some situations.


Layer 3 switches often cost less than traditional routers.
Designed for use within local networks, a Layer 3 switch
will typically not possess the WAN ports and wide area
network features a traditional.

# 3
first of all the differnce between layer2 and layer3 switching:
layer 2 is for peer to peer communication
layer 3 is for process to process communication

A Layer3 switch u can say an enhanced switch with some
routing capabilities
Broadly we can say switch is a devive using hardware to
create network paths whereas a router does same by
CPU's(s/w). As sudeep above mentioned that layer3 switches
use ASIC chips/circuit over microprocessor in routers it
results into Faster speed(min latancy)

The L3 switches are best suited for Lan & routers for
WAN(for optimised performance rather u can use both in any role)

n yeah biggest differnce between them

A L3 switch is capable of routing traffic between only 2
subnets only
but theres no such limitations in case of router
