Which command is the proper command for allowing RIP routing updates to be received on an interface while not allowing them to be sent out of the same interface?
-
Router(config)# passive-interface e0/0
-
Router(config-if)# passive-interface
-
Router(config-if)# interface passive
-
Router(config-router)# passive-interface e0/0
-
Router(config-router)# interface passive e0/0
Explanation:
The correct answer is as follows:Router(config-router)# passive-interface e0/0The effect of the passive-interface command is dependent on the routing protocol running on the interface. For EIGRP, the router will not only stop sending routing updates, but also hellos, which means that it will not form a neighbor relationship with another EIGRP router on that interface. This is also the case with OSPF and IS-IS. With RIP, however, the router will continue to send hellos even as it stops sending routing updates, and it will still receive routing updates.The passive-interface command issued at the router configuration mode will prevent routing updates from being sent out on a specific interface while still allowing the interface to receive updates. This command can be used in any situation where you want the router to receive routing updates on a particular interface but not send any updates. This is helpful for security purposes, for preventing routing loops, or to control routing update traffic.The other options either use improper syntax or are executed at an incorrect prompt.
