Information
Before enabling this feature, enable the enable bgp four-octet-as-
support
command. 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 reflected in the running-configuration. If you
change the notation type, the running-config updates dynamically and the new
notation shows.
