bgpd.pl is a partial implementation of the BGP protocol (RFC1771) in Perl. It
was writen as a tool to monitor BGP routing updates. It is not meant to be used
as a BGP router in an operational network. In fact, it is unable to propagate
routing information because there is no code to send BGP UPDATE messages.
bgpd.pl also does not touch the routing table of the host it runs on.
