Router is software based and L3 Switch is hardware based.
Router dose the software based routing and L3 Switch dose

broadcast.

Answer / saheem shah
L3 switches do not have WAN interfaces.
You can connect Ethernet circuits to a switch so you only
need a router if you want to connect traditional circuits
such as E1 E1 SDH or old technology such as X21 V35 or
async circuits.
As far as I know Call Manager Express does not run on a
switch but does on a router.
Switches support WiFi controller, Firewall so are quite
powerfull.
So you need to understand the business requirement before
deciding router or switch.
Also routers can include switch modules

Answer / krishna.venkata
Layer 3 switch are almost same as a router with following differences
Layer 3 switch is optimized to data as fast as layer2 switch but it makes the decision on how to transmit traffic at layer 3 (just like a router)
Perfect in Lan environment as it is built on switching hardware. Another thing is it is faster than a router in LAN environment. Layer 3 use route once switch many policy. It means when it search for specific destination using a routing table, it creates a cache entry in a switch RAM. So next time it does not have to search again for a routing table for same source and destination address. It also picks up hop information from cache.
So you can say that Layer 3 switch has the ability to reprogram the hardware dynamically with the current Layer 3 routing information. That is why it is faster than a router.
To be frank many of Cisco’s layer 3 switch’s are actually routers
Layer 3 switch good for LAN
Routers good for WAN
Router has some advanced routing functionality which is not available in Layer 3 switch at all.
