for the above it is sufficient to advertise the unreachability for few
seconds from each ABR independently. That would be a much more solid
proposal.
Not sure about "few seconds" ... IBGP def hold time in number of
implementations is 180 sec :) .. but few minutes will work for sure.
depends how you use it.
If you can use the unreachable info in a smart way, it's sufficient if
it is present for a very short time interval.
