Show contents of a ROA table (by default of the first one). You can
specify a <m/prefix/ to print ROA entries for a specific network. If you
use <cf>for <m/prefix/</cf>, you'll get all entries relevant for route
validation of the network prefix; i.e., ROA entries whose prefixes cover
the network prefix. Or you can use <cf>in <m/prefix/</cf> to get ROA
entries covered by the network prefix. You could also use <cf/as/ option
to show just entries for given AS.

Add a new ROA entry to a ROA table. Such entry is called <it/dynamic/

dynamic entries survive reconfiguration.
