Unfortunately, I havent come across IOS version where the default behaviour
is changed. (The default behaviour is to redistribute nothing)/
However, I was following up an earlier thread, wherein someone
observed/commented on this behaviour.
Also, its a simple behaviour, which you can test and see. To be on the safe
side, always use 'match internal/external/nssa' explicitly (that way you
cant go wrong, neither are u dependent on the change in default behaviour)
