What happens when BGP enters the established state?

Explanation:
Entering the established state means the BGP session with the neighbor is fully up and ready to operate. At this point, the TCP connection has been established and the BGP OPEN negotiations have succeeded, so peering is confirmed. With the session established, the routers begin exchanging routing information—UPDATE messages that carry NLRI (the routes) and path attributes—and the learned routes can be installed into the local routing table. This is the moment when peering is active and actual routing data starts to flow between the peers.
