An engineer notices that many BGP peers utilize the same configuration parameters. What can the engineer configure to simplify BGP neighbor statements and generate more efficient BGP peer updates?

The correct answer is A. peer groups. BGP peer groups allow an engineer to group multiple BGP neighbors that share identical configuration parameters (such as update-source, next-hop-self, route policies, timers, etc.) under a single named group. Instead of repeating the same configuration for each neighbor, you…

Explanation

BGP peer groups allow an engineer to group multiple BGP neighbors that share identical configuration parameters (such as update-source, next-hop-self, route policies, timers, etc.) under a single named group. Instead of repeating the same configuration for each neighbor, you apply it once to the peer group. This simplifies the neighbor statements and improves efficiency because the router generates a single BGP update for the entire peer group rather than individual updates per neighbor, reducing CPU and memory overhead.
