[Cisco] Router 與Layer 3 Switch 差異比較表

L3 的交換器又稱為 IP Switch 或 Switch Router，透過專屬的 ASIC 晶片來解析第三層表頭（如 IP Header）以達到傳送目的，因此通常可以提高到每秒百萬封包的效能以及數十個高速 ...

Layer 3 switches are able to route traffic within the local network, while routers connect different networks together. When a packet arrives at ...

Router和L3 Switch經常不容易知道差別在哪裡~. 簡單說Layer 3 Switch 彌補Router 不足之處. 用在Lan的範圍內與Router互補( Inter — vlan Routing).

In theory, a router and a layer 3 switch do the same thing. So in many cases, they are interchangeable (assuming you have the right interfaces).

簡而言之，第三層交換器結合了交換器和路由器的功能。它在交換層面實現高效的子網路或虛擬區域網路（VLAN）內的設備連接，同時能夠整合IP 路由功能，兼作路由器使用。

Routers perform packet switching by microprocessor-based software routing engines, while Layer 3 switches perform packet switching by hardware.

Generally speaking, a layer 3 switch connects hosts to form local area networks (LANs) while routers connect multiple LANs into wide area networks (WANs).

The functionality of router is to connect various networks simultaneously. The main functionality of layer 3 switch is to connect various ...
