The debugging bgp event command is used to enable BGP event debugging,
which is mainly related to events triggering the BGP state machine transitions.
which is mainly related to events triggering the BGP state machine transitions.
After this debugging is enabled, information about all the BGP state machine
transitions and the events triggering these transitions will be displayed. If no BGP
peer relationship can be established, you can enable this debugging to locate the
fault. Enabling debugging may affect system performance; therefore, use this
command only when necessary and disable debugging once the debugging
operation is complete.

By default, BGP event debugging is disabled.
