JNCIP-ENT Interior Gateway Protocols Practice Question
Which TWO actions can you take in Junos OS to optimize OSPF convergence times in a large enterprise network? (Choose two)
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
✓
Configure faster Hello and Dead intervals on transit interfaces.
OSPF convergence can be accelerated by tuning SPF schedule delays (spf-options) and adjusting interface-specific hello and dead intervals.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure faster Hello and Dead intervals on transit interfaces.
Why this is correct
Lowering hello and dead timers allows routers to detect link failures more rapidly.
- ✓
Tune the OSPF SPF delays using the 'set protocols ospf spf-options' hierarchy.
Why this is correct
Adjusting the hold, delay, and rapid intervals under spf-options optimizes how quickly SPF recalculates after topology changes.
- ✗
Disable link-state acknowledgement pacing globally.
Why it's wrong here
Disabling or misconfiguring ACK pacing can lead to packet drops and instability rather than optimized convergence.
- ✗
Convert all backbone areas into completely stubby areas.
Why it's wrong here
The backbone area (Area 0) cannot be configured as a stub or totally stubby area.
- ✗
Increase the SPF hold-down timer to allow network stabilization before running computations.
Why it's wrong here
Increasing hold-down timers slows down convergence, whereas tuning lower delay intervals speeds it up.
