in.rdisc
in.rdisc(1M) System Administration Commands in.rdisc(1M)
NAME
in.rdisc, rdisc - network router discovery daemon
SYNOPSIS
/usr/sbin/in.rdisc [-a] [-f] [-s] [send-address] [receive-address]
/usr/sbin/in.rdisc -r [-p preference] [-T interval] [send-address] [receive-address]
DESCRIPTION
in.rdisc remains part of the software distribution of the Solaris Operating Environment. It is, however, not used by default. in.routed(1M)
includes the functionality provided by in.rdisc. See routeadm(1M) for details of how to specify the IPV4 routing daemon.
in.rdisc implements the ICMP router discovery protocol. The first form of the command is used on hosts and the second form is used on
routers.
in.rdisc can be invoked in either the first form (host mode) or second form (router mode).
On a host, in.rdisc populates the network routing tables with default routes. On a router, advertises the router to all the hosts.
Host (First Form)
On a host, in.rdisc listens on the ALL_HOSTS (224.0.0.1) multicast address for ROUTER_ADVERTISE messages from routers. The received mes-
sages are handled by first ignoring those listed router addresses with which the host does not share a network. Among the remaining
addresses, the ones with the highest preference are selected as default routers and a default route is entered in the kernel routing table
for each one of them.
Optionally, in.rdisc can avoid waiting for routers to announce themselves by sending out a few ROUTER_SOLICITATION messages to the
ALL_ROUTERS (224.0.0.2) multicast address when it is started.
A timer is associated with each router address. The address will no longer be considered for inclusion in the routing tables if the timer
expires before a new advertise message is received from the router. The address will also be excluded from consideration if the host
receives an advertise message with the preference being maximally negative or with a lifetime of zero.
Router (Second Form)
When in.rdisc is started on a router, it uses the SIOCGIFCONF ioctl(2) to find the interfaces configured into the system and it starts lis-
tening on the ALL_ROUTERS multicast address on all the interfaces that support multicast. It sends out advertise messages to the ALL_HOSTS
multicast address advertising all its IP addresses. A few initial advertise messages are sent out during the first 30 seconds and after
that it will transmit advertise messages approximately every 600 seconds.
When in.rdisc receives a solicitation message, it sends an advertise message to the host that sent the solicitation message.
When in.rdisc is terminated by a signal, it sends out an advertise message with the preference being maximally negative.
OPTIONS
-a Accept all routers independent of the preference they have in their advertise messages. Normally, in.rdisc only accepts
(and enters in the kernel routing tables) the router or routers with the highest preference.
-f Run in.rdisc forever even if no routers are found. Normally, in.rdisc gives up if it has not received any advertise message
after soliciting three times, in which case it exits with a non-zero exit code. If -f is not specified in the first form
then -s must be specified.
-r Act as a router, rather than a host.
-s Send three solicitation messages initially to quickly discover the routers when the system is booted. When -s is specified,
in.rdisc exits with a non-zero exit code if it can not find any routers. This can be overridden with the -f option.
-p preference Set the preference transmitted in the solicitation messages. The default is zero.
-T interval Set the interval between transmitting the advertise messages. The default time is 600 seconds.
