Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 216

Which two statements are true about EIGRP manual summarization? (Choose two.)

Answer options

• A. Manual summarization is configured on a per interface basis.
• B. Manual summaries can be configured with the classful mask only.
• C. When manual summarization is configured, autosummarization is automatically disabled by default.
• D. The summary address is assigned an administrative distance of 10 by default.

Correct answer:

Explanation

Option A is correct because manual summarization is applied to specific interfaces. Option B is also accurate, as manual summarization utilizes classful masks. Option C is incorrect because while manual summarization does disable autosummarization, it is not the default behavior for all configurations. Option D is wrong because the default administrative distance for a summary route is 5, not 10.
