In EIGRP, which command would you use to set an interface to passive mode?

• A. passive-interface
• B. no eigrp interface
• C. disable-interface
• D. stop-routing

Answer: (A)

Setting an interface to passive mode in EIGRP (Enhanced Interior Gateway Routing Protocol) is accomplished using the command designed specifically for that purpose: the passive-interface command. When an interface is in passive mode, it will not send EIGRP hello packets or participate in the EIGRP routing process, which is particularly useful for interfaces that connect to end hosts or are not meant to form EIGRP neighbor relationships. This helps reduce unnecessary EIGRP traffic and enhances network stability and security by preventing EIGRP from sending routing updates on those interfaces. The other choices do not serve the function of placing an interface into passive mode. Commands like "no eigrp interface," "disable-interface," and "stop-routing" either do not exist in the context of EIGRP configuration or are not relevant to the action of setting an interface to passive mode, making them ineffective for this particular requirement.
