Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 234

You have implemented mutual route redistribution between OSPF and EIGRP on a border router. When checking the routing table on one of the EIGRP routers within the EIGRP routing domain, you are seeing some, but not all of the expected routes. What should you verify to troubleshoot this problem?

Answer options

• A. The border router is using a proper seed metric for OSPF.
• B. The border router is using a proper seed metric for EIGRP.
• C. The administrative distance is set for OSPF and EIGRP.
• D. The missing OSPF routes are present in the routing table of the border router.

Correct answer: O, S, P, F

Explanation

The correct answer is D because if the missing OSPF routes are not present in the routing table of the border router, they cannot be redistributed into EIGRP. Option A refers to the seed metric for OSPF, which is not relevant if the routes are not available to begin with. Option B discusses the seed metric for EIGRP, which does not apply here either, as the issue is with missing OSPF routes. Option C mentions administrative distance, which does not directly influence the availability of routes for redistribution.
