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
✓
show ip bgp <prefix>
To verify BGP advertisement to a neighbor, 'show ip bgp neighbors <neighbor> advertised-routes' shows all routes advertised to that neighbor. 'show ip bgp <prefix>' includes an entry for each neighbor the route is advertised to. 'show ip bgp neighbors <neighbor> routes' shows routes received from the neighbor, not advertised. 'debug ip bgp updates' is a debug command, not a verification command. 'show ip bgp summary' shows neighbor states and counts, not specific prefix advertisement.
