Prefix instances using the new format include both unique identifiers, and ordinals to control path selection. Withdrawal of prefixes requires a slight modification to disambiguate prefix instances.Author's Note This Internet Draft is intended to result in this draft or a related draft(s) being placed on the Standards Track for idr.
