NAME
ip6rtrd - IPv6 routing daemon
SYNOPSIS
/usr/sbin/ip6rtrd [-dD] [-l logfile] [configfile]
OPTIONS
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. 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 spec-
ify a log file, information is logged to stdout.
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 parame-
ter.
Signals
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 broad-
casts 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.
