To display BGP standard communities in AA:NN format, use the ip bgp-community
new-format command in Global Configuration mode. RFC 1997 specifies that the first two
bytes of a community number are considered to be an autonomous system number. The new
format displays a community number as the ASN followed by a 16-bit AS-specific number.
Default Standard communities are displayed in AA:NN format.
