Re: 2000::/6

hey,

Any decent router won't allow you to enter just anything in that range into the export rules with a /6, except 2000:: itself, and will even show you a failure response instead of silently ignoring the invalid input, for the very purpose of helping you avoid such errors.

IOS was already brought up, luckily Junos and TIMOS do just that (both for prefix-lists and static routes). Unfortunately directly connected networks remain and there is no way to solve that. -- tarko
