ip6rtrd(8)


NAME

  ip6rtrd - IPv6 routing daemon


SYNOPSIS

  /usr/sbin/ip6rtrd [-dDm] [-l logfile] [configfile]


OPTIONS

  -d  Enables additional debugging information, such as bad packets received,
      to be logged. The ip6rtrd daemon remains under control of the host that
      started it; therefore, an interrupt from the controlling host stops the
      ip6rtrd process.

  -D  Same as the -d option, but does not run as a daemon.

  -l logfile
      Specifies a log file into which ip6rtrd writes information about its
      actions. The log contains information about any changes to the routing
      tables and a history of recent route change messages sent and received
      that are related to changed routes. If you do not specify a log file,
      information is logged to stdout.

  -m  Specifies that ip6rtrd is running in a location where mobile nodes
      might be present.	 The daemon will immediately respond to Router
      Solicitation (RS) packets in order to improve movement detection of the
      mobile nodes.


DESCRIPTION

  The ip6rtrd daemon sends IPv6 Router Advertisement (RA) packets of the
  Neighbor Discovery Protocol. These packets enable any listening host to
  autoconfigure itself without manual intervention. In addition, you can
  configure ip6rtrd to send and process RIPng messages.

  At startup, the ip6rtrd daemon reads its default configuration file for
  startup information. If you used ip6_setup to configure IPv6 on your
  system, the configuration file is /etc/ip6rtrd.conf. You can specify an
  alternate configuration file by using the configfile parameter.

  Signals

  The following signals have the specified effect when sent to the ip6rtrd
  process using the kill(1) command:

  SIGUSR1
      Displays internal routing tables. If a log file is specified, the
      routing information is logged to it.

  SIGTERM
      Terminates the ip6rtrd process. Before exiting, the daemon removes any
      system state that was configured by the daemon, including default
      routers and on-link prefixes.  In addition, the daemon broadcasts RIPng
      packets with hop counts set to infinity over the appropriate
      interfaces.

				      Caution

	 Do not use SIGKILL to terminate the ip6rtrd process, as this may
	 leave the system's IPv6 configuration in an inconsistent state.


RESTRICTIONS

  Do not run the nd6hostd and ip6rtrd daemons on the same host as this may
  produce unpredictable results.
