Which Junos OS operational mode command provides a high-level view of all configured BGP peers?

The command that provides a high-level view of all configured BGP peers is "show bgp summary." This command gives an overview of the BGP session status, including the state of each peer, the number of prefixes received, and the overall performance of the BGP sessions. It succinctly summarizes the BGP router's operational state, allowing administrators to quickly assess the connectivity and health of their BGP peers.

While other commands may provide more detailed or specific information about individual neighbors or BGP groups, they do not deliver the same comprehensive snapshot as "show bgp summary." For instance, the command related to showing BGP neighbors focuses on specific peer details rather than an overall summary, making it less suitable for getting a quick overview of all BGP configurations at once.
