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
✓
set protocols ospf area 0.0.0.1 area-range 10.10.0.0/16
Internal route summarization on an OSPF ABR in Junos is configured using the 'area-range' statement under the specific area hierarchy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
set protocols ospf summary 10.10.0.0/16 area 0.0.0.1
Why it's wrong here
The summary keyword is not used this way in Junos OSPF.
- ✗
set protocols ospf area 0.0.0.1 aggregate 10.10.0.0/16
Why it's wrong here
Aggregate is used in BGP routing policies, not OSPF area configuration.
- ✗
set routing-options aggregate route 10.10.0.0/16 ospf
Why it's wrong here
Aggregate routes belong in routing-options but are exported via policy, whereas OSPF internal summarization uses area-range.
- ✓
set protocols ospf area 0.0.0.1 area-range 10.10.0.0/16
Why this is correct
The 'area-range' command summarizes routes advertised from the specified area into the backbone or other areas.
