An administrator implements OSPF on a Junos router with virtual links to span a disconnected non-backbone area across a non-backbone transit area to reach Area 0. What is a key design best practice regarding OSPF virtual links in enterprise networks?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
They should be avoided in permanent designs due to troubleshooting complexity and lack of stability.
Virtual links should be used strictly as temporary or fallback solutions because troubleshooting them is complex, and they introduce fragility into the OSPF backbone topology.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
They must be configured with a metric of 1 to ensure primary path selection.
Why it's wrong here
Incorrect. Virtual link metrics are based on the actual path cost through the transit area and cannot be arbitrarily set to 1 easily.
- ✓
They should be avoided in permanent designs due to troubleshooting complexity and lack of stability.
Why this is correct
Correct. Virtual links are considered a design workaround and are best avoided in stable, well-architected networks.
- ✗
They automatically convert the transit area into an extension of the backbone.
Why it's wrong here
Incorrect. The transit area remains a normal non-backbone area.
- ✗
They require the transit area to be configured as a totally stubby area.
Why it's wrong here
Incorrect. The transit area for a virtual link must be a standard area, never a stub or NSSA.
