JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2024) — Question 51

What are two similarities between OSPFv2 and OSPFv3? (Choose two.)

Answer options

• A. virtual links
• B. support for multiple instances per link
• C. 32-bit router ID
• D. protocol processing per link, not per subnet

Correct answer: A, C

Explanation

The correct answers are A and C because both OSPFv2 and OSPFv3 utilize virtual links and share a 32-bit router ID for identifying routers. Option B is incorrect as OSPFv2 does not support multiple instances per link, and option D is misleading as protocol processing is consistent across both versions.
