Which command displays the overall status of all BGP connections?

Explanation:
To quickly gauge the health of all BGP sessions, you need a single view that lists every peer and the state of its connection. show ip bgp summary provides exactly that: a concise list of all neighbors with their remote AS, the current session state (Idle, Connect, Active, OpenSent, OpenConfirm, Established), how long the session has been up, and how many prefixes have been received from each neighbor. This lets you see at a glance whether all BGP connections are up and exchanging routes. Other commands focus on different information. show ip bgp displays the actual BGP routing table entries learned via BGP, not the status of the peer sessions. show ip route shows the overall routing table, including any BGP-originated routes, but not the health of individual BGP sessions. show bgp neighbors (depending on the platform) can give per-neighbor detail, but it isn’t the compact, unified summary that reveals the overall status of all connections.
