Designing Cisco Network Service Architectures (ARCH, legacy) — Question 10

Two companies want to merge their OSPF networks, but they run different OSPF domains. Which option must be created to accomplish this requirement?

Answer options

• A. OSPF virtual link to bridge the backboneareas of the two companies together
• B. Area on the ASBR of each company with the same area ID to bridge the networks together
• C. redistribute routes between domains
• D. NSSA on the ASBR of each company

Correct answer: C

Explanation

The correct answer is C because redistributing routes between different OSPF domains allows for the integration of the two networks. Options A and B focus on specific configurations that do not facilitate inter-domain communication, while option D involves NSSA, which is not necessary for merging distinct OSPF domains.
