A. B. C. D.C
If a BGP-learned prefix is not being installed in the routing table, it could be due to a number of reasons such as a filtering policy, a routing policy or a configuration issue. To determine the cause of the issue, you need to identify the route that is not being installed in the routing table.
Out of the given options, the command that shows the missing route is "C. show route hidden extensive". This command displays the routes that are not selected for installation in the routing table. The "hidden" routes are those that do not meet the routing table installation criteria, such as route preference, metric or policy.
Option A, "show route advertising-protocol bgp", displays the routes that are being advertised by BGP, not the missing routes.
Option B, "show route state", displays the state of the route, such as active or inactive, but it does not show the missing route.
Option D, "show bgp summary", displays the summary of BGP routing information, such as the number of BGP routes received, but it does not show the missing route.
Therefore, option C is the correct command to use to identify the missing BGP-learned prefix.
