There is no plan in adding route flap dampening as in RFC 2439. Even RIPE reconsidered there position about it and is now considering it evil. Especially RFC 2439 does not help that much because it penalizes only prefixes that are withdrawn from the RIB. Additionally it is unclear what you mean with "much up/down". There is already a flap dampening for sessions implemented. Finally packet forwarding should be mostly unaffected by userland CPU usage as it runs with much higher priority in the kernel. -- :wq Claudio
