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).
