MCSE Interview Question:

What is the difference between L3 Switch and Router, if they perform the same function why do we need both of them?

Submitted by: Administrator

Layer 3 switches do routing with ASIC chips. Routers do it with a microprocessor and its associated software. Therefore, the Layer 3 switches are much faster than traditional but cost more. We need them both because in many situations a slow router is sufficient and cheaper than a gigabit layer 3-switch router.
