You need configure IPX basic functions before this task.
n
IPX RIP and SAP periodically broadcast updating packets. With the triggered
■
updating feature enabled, updating packets will be sent upon route or service
information changes. Thus, flooding of broadcasts can be avoided.
Split horizon is a way to avoid routing loops, that is, routing information
■
received from an interface is not permitted to be sent from the interface. In
some cases, split horizon must be prohibited to ensure correct routing
information transmission. In addition, split horizon prohibition does not take
effect on point-to-point links.
The type 20 IPX packet is used in NetBIOS. You can either prohibit or permit the
■
forwarding of type 20 broadcast packets based on the actual requirements.
