Hardware Routing Table Management

The switch hardware can route traffic based on information stored in hardware and software 
routing tables. Routing tasks are completed much faster when the routes are already stored 
in hardware routing tables. When packets are routed using the hardware routing tables, this 
is called fast-path routing, because the packets take the fast path through the switch.

The switch hardware provides the fast path, and the XCM8800 software provides the routing 
management capabilities, including management of the hardware routing tables. The 
software collects all routing information, manages the routes according to the switch 
configuration, and stores the appropriate routes in the hardware routing tables. When an IP 
unicast packet arrives and the destination IP address is not found in the hardware route 
tables, it is routed by software. The software processing takes more time than the fast path, 
so routing based on the software tables is called slow-path routing.

NETGEAR 8800 switches allow you to customize the software management of the hardware 
routing tables using the following hardware components:
