If the old provider is advertising the prefix based on your advertisement to them (you're running BGP), then their advertisement should cease shortly after your link to them goes down. Likewise, the new provider would only propagate the advertisement after you advertise it to them. Michael H.

The "new" provider is telling us that they can start announcing, without us having to tell the old provider to stop announcing. I.e., a 2-3 day period where both are announcing our class C. This conflicts with my extremely (admittedly)limited knowledge. Can someone let me know if this is OK/not OK? Thanks in advance, Mike Michael Donahue WATG (949) 574-8500 x261
