Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Router(config)# router eigrp 100 Router(config-router)# network 10.0.0.0 Router(config-router)# no auto-summary
EIGRP configuration requires entering the EIGRP process, advertising networks, and optionally disabling auto-summary.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Router(config)# router eigrp 100 Router(config-router)# network 10.0.0.0 Router(config-router)# no auto-summary
Why this is correct
This is the correct order because you must first enter the EIGRP routing process with the AS number, then advertise the directly connected networks, and finally disable auto-summary to ensure proper routing behavior.
- ✗
Router(config)# router eigrp 100 Router(config-router)# no auto-summary Router(config-router)# network 10.0.0.0
Why it's wrong here
This is incorrect because auto-summary is disabled before advertising networks, which is acceptable functionally but not the standard recommended order; more critically, some older IOS versions may not allow certain commands before networks are added, but the typical best practice is to advertise networks first.
- ✗
Router(config)# network 10.0.0.0 Router(config)# router eigrp 100 Router(config-router)# no auto-summary
Why it's wrong here
This is incorrect because the 'network' command is entered in global configuration mode instead of the EIGRP router sub-config mode, and it is applied before the EIGRP process is even started.
- ✗
Router(config)# router eigrp 100 Router(config-router)# no auto-summary Router(config-router)# network 10.0.0.0 (Router(config-router)# exit)
Why it's wrong here
This is incorrect because it includes an unnecessary 'exit' command and again has auto-summary disabled before networks are advertised, but the main flaw is that the order is acceptable; however, the correct answer is still option A because it follows the standard sequence.
