My apologies if this question doesn't belong here. We have a PI /24 we'd like to advertise out of our primary data center for production use. (Well, actually, we'll be advertising a more specific from our /21 assignment, so already not too friendly... but I digress.) We have a disaster recovery site which will have a clone of the myriad production servers. We'd like to fail over to that site automagically. I'm thinking advertising the same prefix and just doing several as-prepends. However, now I'm not sure if this is a polite thing to do or not. Someone mentioned to me something with MEDs, but as soon as that term was used, I started twitching, and couldn't follow the conversation. Would a "good netizen" use the as-prepend method? Or am I missing a simpler/more polite solution? -Christopher
