Withdrawls and announcements attempt 2

There are however vendors out there that do exactly what you described
above and can therefore change policies and have them take effect
without having to take down a BGP session.

Like cisco, for example, with the new soft reconfiguration stuff.

C'mon Marten, I expect better than this type of marketing crap from you.

And they only withdraw a
prefix if they sent an update for it in the first place.

-> BGP list please.
