ip6rtrd - IPv6 routing daemon
/usr/sbin/ip6rtrd [-dD] [-l logfile] [configfile]
-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.
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.
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 sys-
tem, the configuration file is /etc/ip6rtrd.conf. You can specify an
alternate configuration file by using the configfile parameter.
The following signals have the specified effect when sent to the ip6rtrd
process using the kill(1) command:
Displays internal routing tables. If a log file is specified, the
routing information is logged to it.
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 inter-
Do not use SIGKILL to terminate the ip6rtrd process, as this may
leave the system's IPv6 configuration in an inconsistent state.
Do not run the nd6hostd and ip6rtrd daemons on the same host as this may
produce unpredictable results.
Commands: ifconfig(8), ip6_setup(8).
