Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 168

Users report issues with reachability between areas as soon as an engineer configured summary routes between areas in a multiple area OSPF autonomous system.
Which action resolves the issue?

Answer options

• A. Configure the area range command on the ASBR.
• B. Configure the summary-address command on the ASBR.
• C. Configure the summary-address command on the ABR.
• D. Configure the area range command on the ABR.

Correct answer: D

Explanation

The correct action is to configure the area range command on the ABR, as it allows for proper summarization of routes between different OSPF areas. The other options either involve the ASBR, which is not responsible for inter-area summarization, or suggest using the summary-address command, which does not apply to area summarization in this context.
