Usage Information
Before enabling this feature, enable the enable bgp four-octet-as-supportcommand. If you disable the
four-octect-support command after using dot or dot+ format, the AS numbers revert to asplain text.
When you apply an asnotation, it is reected in the running-conguration. If you change the notation type, the
running-cong updates dynamically and the new notation shows.
