JNCIP-ENT BGP Advanced Practice Question
A network administrator wants to advertise an aggregate BGP route while suppressing the more specific component routes from being sent to external peers. Which Junos routing-options configuration achieves this?
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 the aggregate route with the 'summary-only' parameter under routing-options bgp.
Using the 'aggregate' statement with the 'summary-only' option generates the aggregate prefix and suppresses all component specific routes.
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 the aggregate route with the 'summary-only' parameter under routing-options bgp.
Why this is correct
The 'summary-only' parameter suppresses specific component routes when advertising the aggregate prefix.
- ✗
Enable BGP dampening on the aggregate route and disable it on the component routes.
Why it's wrong here
Route dampening handles flapping routes, not route aggregation suppression.
- ✗
Apply a routing policy that sets the NO_EXPORT community on all component routes.
Why it's wrong here
NO_EXPORT prevents external advertisement but still passes routes to internal IBGP peers, whereas summary-only suppresses them entirely from the specified exports.
- ✗
Configure an aggregate route with the 'discard' policy and apply an export policy that drops component routes.
Why it's wrong here
While manual filtering works, Junos provides a native 'summary-only' option specifically for this purpose.
