Which command would you use to display the EIGRP protocols running on your router?

  1. show eigrp neighbors

  2. show ip protocols

  3. router eigrp AS NUMBER

  4. passive-interface INTERFACE NUMBER

The correct answer is: show ip protocols

The command that displays the EIGRP protocols running on your router is “show ip protocols.” This command provides detailed information about the current routing protocols configured on the router, including EIGRP. It will show you the routing protocol settings, such as the EIGRP autonomous system number, network statements, and any timers associated with the protocol. While viewing EIGRP neighbors can provide insight into the devices your router is communicating with, it does not directly show the configuration of the EIGRP protocol itself. Other commands like configuring EIGRP or setting interfaces to passive mode serve specific purposes related to EIGRP operation but do not provide a summary of the EIGRP protocols in use. Thus, “show ip protocols” is the most comprehensive command for understanding EIGRP's status and configuration on the router.
