argument to the regular expression, output filtering is possible:
host1#show ip bgp quote-regexp ^200 | begin Prefix

You can use the field options to display filtered information about BGP neighbors.
If you filter the display with field options, the usual introductory information
about BGP attributes is displayed only if you issue the intro fields option. See
show ip bgp for descriptions of the fields displayed by this keyword.
You can use the default-fields peer command to specify default fields to be
displayed by subsequently issued show ip bgp summary commands.
