13.1 Introduction to IP Route
Route function is one of the important functions of three-layer switch, which can realize the
speedy route forwarding in different IP network. iSpirit 3026 is a kind of double-layer switch
without three-layer forwarding function, but it can visit different network devices through other
three-layer device. There are three ways to realize route
●
Default Route: lead the data flow to some specific exit when the data flow’s purpose
address is unknown
●
Static Route
●
Configured route appointed by user, which make the data flow be output to some
Internet from specific port along single route
●
Dynamic Route: make account for the best route through dynamic route protocol and
tranfer the data flow
1. Interface Configuration
For configuring IP route, there must be three-interface to distribute IP address, after that the host
machine in the three-interface can be communicated with host machine in other three-layer
interface. Some specific address cannot be distributed to the three-layer interface. For details
please refer to Table 13-1:
