I should clarify here:

A subsequent run of the BGP resdistribution process with the 
newly rewritten policy in place resulted in the routes being 
tagged with the appropriate "keep internal" community and "re-
advertised".  Upon receipt of the now tagged routes, routers that
had previously announced the untagged routes withdrew them (per 
egress policy specification).
