What's the BGP route active received accepted damped status meaning?

is the active received accepted damped special to BGP route or just normal route's status?

Answer 1

The Juniper documentation here actually words this well.

In summary, that is a multipurpose field used to display information about BGP peer sessions. The field’s contents depend upon whether a session is established and whether it was established on the main routing device or in a routing instance.

If a peer is not established, it will show the state of the peer session e.g Active, Connect, or Idle.

If the session is established, the field shows the number of active, received, accepted, and damped routes that are received from a neighbour (inet.0 and inet.2)
