Unfortunately this is by design, people who designed BGP traps were dreadfully
confused what people need. Now you must save previous BGP state in your NMS, so
you are able to determine what happened.

However some platforms, like IOS, extend standard BGP traps and include
'previous state' field, this will allow you to react only on establihes->down
and X->established events, without saving states in NNS. Some other platforms,
like JunOS unfortunately do not provide you with this luxory.
