JNCIP-ENT BGP Advanced Practice Question
An engineer is configuring BGP route resolution and next-hop tracking in Junos. Which TWO circumstances will cause a BGP next hop to be marked as unresolved or unusable? (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
✓
The resolving route in the IGP routing table points to a discard or reject dead-end route.
BGP next hops become unusable if the resolving route in the IGP table is missing, points to a discard/reject route, or lacks reachability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The BGP next-hop IP address matches a directly connected interface subnet on the router.
Why it's wrong here
Directly connected next hops resolve successfully.
- ✗
The BGP neighbor session is established over a loopback interface using multihop.
Why it's wrong here
Loopback multihop sessions resolve correctly as long as an IGP route to the loopback exists.
- ✗
The resolving route has an active loop-free alternate backup path installed.
Why it's wrong here
LFA backup paths enhance resolution and speed, rather than breaking it.
- ✓
The resolving route in the IGP routing table points to a discard or reject dead-end route.
Why this is correct
Discard or reject resolving routes invalidate BGP next-hop resolution.
- ✓
No active route exists in the routing table to reach the BGP next-hop address.
Why this is correct
Lack of a routing table entry for the next hop prevents resolution.
