Welcome to the first trivia question! This is a question that relates to BGP to the extent that it’s covered on the CCNP Enterprise Routing concentration (300-410 – ENARSI).
Better luck next time!
#1 What configuration command is required for BGP to advertise the enhanced route-refresh capability to its neighbors (assuming it’s supported)?
You don’t need to enable route-refresh on a BGP neighbor for the capability to be advertised in the BGP open message (assuming, of course, that route refresh is supported on the router/version of IOS). This is in contrast to soft reconfiguration, which does require such a configuration (neighbor x.x.x.x soft-reconfiguration inbound) due to soft-reconfiguration’s increased intricacy with the separate memory tables that it needs to perform graceful BGP refreshes.
