When using 'set ip next-hop verify-availability', what mechanism does the router use to determine if the next-hop is reachable?
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
✓
It uses a tracked object that can be based on IP SLA, interface state, or other criteria.
The 'verify-availability' option uses a tracked object (configured with the 'track' command) which can be based on IP SLA, interface line-protocol, or other criteria. It does not use ARP or ICMP by default.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It sends an ICMP echo request to the next-hop every 10 seconds.
Why it's wrong here
That would require an IP SLA configuration; verify-availability uses a track object that must be defined separately.
- ✗
It checks the ARP table for the next-hop MAC address.
Why it's wrong here
ARP is not used for reachability verification in this context.
- ✓
It uses a tracked object that can be based on IP SLA, interface state, or other criteria.
Why this is correct
The track object defines the condition; if the track is up, the next-hop is considered reachable.
- ✗
It performs a recursive routing table lookup to see if the next-hop is reachable.
Why it's wrong here
That is normal routing; verify-availability adds an additional check via tracking.
