May not have gotten into any draft, but keeping routing live has certainly been an assumed requirement for some of us. :) > In mooted transfers of resources from one company on one side of the > world and under RIR 1 to a company on the other side of the world > under RIR 2 I really don't see that a make before break argument > applies.

Think about corporate acquisitions for a moment. EngulfAndDevour, headquartered in region A, buys MomAndPopISP, in region B. MomAndPopISP is a going concern whose founders want to retire, grow tomatoes, and deal with no unit of time shorter than a season. EngulfAndDevour has paid heavily for good will of MomAndPopISP's customer base and wants MomAndPopISP's routing to continue to work during transfer of MomAndPopISP's resources from region B to region A. Any downtime at all is unacceptable. Hence make-before-break. _______________________________________________ sidr mailing list [email protected] https://www.ietf.org/mailman/listinfo/sidr
