The rrenumd utility transmits router renumbering request packets, to renumber the routers in the site network.
On KAME-based systems, router renumbering requests are received and processed by rtadvd(8). For other systems, refer to relevant documents.
The program will daemonize itself on invocation. It reads configuration information from standard input if -s is specified, or from conf_file if -c conf_file is specified.
The contents of configuration information are described in rrenumd.conf(5).
After successful configuration, rrenumd sends router renumbering messages periodically to configured destinations. Messages contain prefixes configured to be renumbered.
