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. SEE ALSO

in.ndpd - daemon for IPv6 autoconfiguration SYNOPSIS
/usr/lib/inet/in.ndpd [-adt] [-f config_file] DESCRIPTION
in.ndpd provides both the host and router autoconfiguration components of Neighbor Discovery for IPv6 and Stateless and Stateful Address Autoconfiguration for IPv6. In particular, in.ndpd implements: o router discovery; o prefix discovery; o parameter discovery; o invocation of stateful address autoconfiguration; o stateless address autoconfiguration; and o privacy extensions for stateless address autoconfiguration. Other aspects of Neighbor Discovery are implemented by ip6(7P), including: o address resolution; o neighbor unreachability detection; and o redirect. The duplicate address detection function is implemented by the system kernel. in.ndpd is managed by the service management facility (SMF), by means of the service identifier: svc:/network/routing/ndp:default If the /etc/inet/ndpd.conf file does not exist or does not set the variable AdvSendAdvertisements to true for a network interface, then in.ndpd will make the node a host for that interface, that is, sending router solicitation messages and then using router advertisement messages it receives to autoconfigure the node. Note that in.ndpd only autoconfigures the addresses of global or site-local scope from the prefix advertisement. If AdvSendAdvertisements is set to true for an interface, then in.ndpd will perform router functions on that interface, that is, sending router advertisement messages to autoconfigure the attached hosts, but not use any advertisements it receives for autoconfiguration. How- ever, when sending advertisements, in.ndpd will use the advertisements it sends itself to autoconfigure its prefixes. Stateless autoconfiguration requires no manual configuration of hosts, minimal (if any) configuration of routers, and no additional servers. The stateless mechanism enables a host to generate its own addresses and uses local information as well as non-local information that is advertised by routers to generate the addresses. in.ndpd will plumb logical interfaces for each of these addresses. Stateful autoconfiguration involves the dhcpagent(1M) daemon and the use of the DHCPv6 protocol. The dhcpagent daemon is responsible for plumbing the logical interfaces for the acquired addresses, maintaining the leases, and handling duplicate addresses. in.ndpd starts the dhcpagent daemon automatically and signals when DHCPv6 should be started. in.ndpd also detects when dhcpagent configures the logical inter- faces, and sets the appropriate prefix length on each according to received Routing Advertisement messages. in.ndpd will not stop dhcpa- gent; use ifconfig(1M) to control dhcpagent if necessary. Temporary addresses that are autoconfigured for an interface can also be implemented. A temporary address token is enabled for one or more interfaces on a host. However, unlike standard, autoconfigured IPv6 addresses, a temporary address consists of the site prefix and a ran- domly generated 64 bit number. This random number becomes the interface ID segment of the IPv6 address. A link-local address is not gener- ated with the temporary address as the interface ID. If the kernel detects a duplicate temporary address, in.ndpd will automatically choose another. Routers advertise all prefixes that have been assigned on the link. IPv6 hosts use Neighbor Discovery to obtain a subnet prefix from a local router. Hosts automatically create IPv6 addresses by combining the subnet prefix with an interface IDs that is generated from an interface's MAC address. In the absence of routers, a host can generate only link-local addresses. Link-local addresses can only be used for communication with nodes on the same link. For information on how to enable IPv6 address autoconfiguration, see OPTIONS
Supported options and equivalent SMF service properties are listed below. SMF service properties are set using a command of the form: # routeadm -m ndp:default key=value -a Turn off stateless and stateful address auto configuration. When set, the daemon does not autoconfigure any addresses and does not renumber any addresses. This option does the same thing as the following lines in ndpd.conf(4): ifdefault StatefulAddrConf off ifdefault StatelessAddrConf off Use of this option is equivalent to setting the stateless_addr_conf property to false. -d Turn on large amounts of debugging output on stdout. When set, the program runs in the foreground and stays attached to the controlling terminal. Use of this option is equivalent to setting the debug property to true. -f config_file Use config_file for configuration information instead of the default /etc/inet/ndpd.conf. Use of this option is equivalent to setting the config_file property to the configuration file to be used. -t Turn on tracing (printing) of all sent and received packets tostdout. When set, the program runs in the foreground and stays attached to the controlling terminal. As such, this option cannot be run under the SMF. FILES
/etc/inet/ndpd.conf Configuration file. This file is not necessary on a host, but it is required on a router to enable in.ndpd to adver- tise autoconfiguration information to the hosts. ATTRIBUTES

Receipt of a SIGHUP signal will make in.ndpd restart and reread /etc/inet/ndpd.conf. NOTES
The in.ndpd daemon service is managed by the service management facility, smf(5), under the service identifier: svc:/network/routing/ndp:default Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M) or routeadm(1M).
