Enterasys Networks VH-8G-L3 manual Functions of a Layer 3 Switch

Page 17

The VH-8G-L3 can be thought of as eight Gigabit Ethernet Layer 2 switching domains with a wire-speed router between each domain. It can be deployed in a network between a traditional router and the intranetwork. The traditional router and its associated WAN interface would then handle routing between the intranetwork and the WAN (the Internet, for example) while the Layer 3 switch would handle routing within the LAN (between the Fast Ethernet Layer 2 domains).

The VH-8G-L3 can also replace key traditional routers for data centers and server farms, routing between these locations and the rest of the network, and providing 8 ports of Layer 2 switching performance combined with wire-speed routing.

The Functions of a Layer 3 Switch

Traditional routers, once the core components of large networks, became an obstacle to the migration toward next- generation networks. Attempts to make software-based routers forward packets more quickly were inadequate.

A layer 3 switch does everything to a packet that a traditional router does:

• Determines forwarding path based on Layer 3 information

• Validates the integrity of the Layer 3 header via checksum

• Verifies packet expiration and updates accordingly

• Processes and responds to any optional information

• Updates forwarding statistics in the Management Information Base

• Applies security controls

 

A Layer 3 switch can be placed anywhere within a network
