  -a             convert all entries (default: convert only first entry per
                 one prefix)
  -s             convert only entries from a single asn (the peer asn, specify
                 as -p PEER_ASN)
  -A             convert to ExaBGP API format
  -G [NUM]       convert to ExaBGP API format and group updates with the same
                 attributes for each spceified the number of prefixes using
                 "announce attributes ..." syntax (default: 1000000)
  -P             convert to ExaBGP API program

Result (Config format)

Without "-A"/"-G"/"-P" options, it outputs a ExaBGP config.

Result in "-G" option (API grouping format)

This option is possible to improve the performance, especially when advertising huge prefixes like full internet routes.

It outputs with "announce attributes ..." syntax.

If you use MRT format data included "BGP4MP" or "BGP4MP_ET", you must use this option.

In that case "NUM" argument is ignored even if specified it.
