Multilayer Switching And Fault Tolerance

What Is Multilayer Switching?

Multilayer switches are devices that switch and route packets in the switch hardware itself. These switches can perform packet switching up to ten times as fast as a pure L3 router Cisco Catalyst switches perform hardware switching using a router processor or L3 engine Routing information is downloaded to the hardware itself Hardware-based switching happens using one of the following methods: Cisco Express Forwarding (CEF) Newer method Multilayer Switching (MLS) ß Legacy Application-Specific Integrated Circuits (ASICs) will perform the L2 rewriting operation of hardware switched packets. L2 rewriting process changes the . . . → Read More: SWITCH Study Notes – Multilayer Switching And Fault Tolerance
