Description (partial)

ACI fabric raises the critical event E4208052 "Operation errors internal error in BGP instance"

"Inconsistent flags" messages are logged in "show bgp internal event-history logs"

This is happening because a BGP route is not programmed in hardware yet, at the time when we received the URIB acknowledgement for this route. This is a very timing-based transient scenario.
