Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 178

By default, which statement is correct regarding the redistribution of routes from other routing protocols into OSPF?

Answer options

• A. They will appear in the OSPF routing table as type E1 routes.
• B. They will appear in the OSPF routing table as type E2 routes.
• C. Summarized routes are not accepted.
• D. All imported routes will be automatically summarized when possible.

Correct answer:

Explanation

The correct answer is B, as by default, routes from other routing protocols that are redistributed into OSPF are classified as type E2. Option A is incorrect because type E1 routes represent a different calculation method. Options C and D are also wrong since OSPF does accept summarized routes and does not automatically summarize all imported routes.
