AS announcement question (easy)

[Mike Donahue <mdonahue () WATG com>]

Hi, sorry for this low-level question, but at least I'm not posting in html.
:)

My company owns a class C, and we're switching ISPs.  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
