Disabling an Interface from Receiving Packets
If an interface does not need to learn routing information from neighbors, you can disable the interface from receiving RIP packets.
Usage Scenario
On an enterprise network where departments are not allowed to communicate with each other, you can disable interfaces from receiving packets.
On the network shown in Figure 1, if you do not want Department 1 to learn routing information about Department 2, you can disable the interface on Device A from receiving packets.
