Which three route filtering statements are true? (Choose three)

A. After the router rip and passive-interface s0/0 commands have been issued, the s0/0 interface will not send any RIP updates, but will receive routing updates on that interface.

B. After the router eigrp 10 and passive-interface s0/0 commands have been issued, the s0/0 interface will not send any EIGRP updates, but will receive routing updates on that interface

C. After the router ospf 10 and passive-interface s0/0 commands have been issued , the s0/0 interface will not send any OSPF updates, but will receive routing updates on that interface

D. When you use the passive-interface command with RIPv2, multicasts are sent out the specified interface

E. When you use the passive-interface command with EIGRP, hello messages are not sent out the specified interface

F. When you use the passive-interface command with OSPF, hello messages are not sent out the specified interface




 

Suggested Answer: AEF

Passive-interface command is used in all routing protocols to disable sending updates out from a specific interface. However the command behavior varies from o- ne protocol to another"
-- In RIP, this command will not allow sending multicast updates via a specific interface but will allow listening to incoming updates from other RIP speaking neighbors. This means that the router will still be able to receive updates on that passive interface and use them in its routing table.
-- In EIGRP and OSPF the passive-interface command stops sending outgoing hello packets, hence the router can not form any neighbor relationship via the passive interface. This behavior stops both outgoing and incoming routing updates.
