This is currently impossible and a carp setup will not help you as it will take the same amount of time to take over. I have some evil plans with rfc4724 "Graceful Restart Mechanism for BGP" but this is still far away from being implemented because this depends on stuff that is slowly developped at the moment. Your best approach is to use two routers and split the peers between the two. If one fails you still have the other left. -- :wq Claudio
