Loading Routing Information at Boot Time

When a Trusted Solaris host boots, it loads routing information so it can transmit data. If the file /etc/tsolgateways (which is maintained manually by the administrator) exists, then the gateways in the file serve as the host's defaults. If, however, /etc/tsolgateways does not exist, then the host uses the default routes from the file /etc/defaultrouter, which is also maintained manually by the administrator. If either file exists, then the host is said to use static routing.

If neither the /etc/tsolgateways nor the /etc/defaultrouter file exists, then the host uses dynamic routing and must start a special daemon, either in.rdisc(1M) (the network router discovery daemon) or in.routed(1M) (the network routing daemon). If the host also serves as a gateway (that is, a host that connects to two or more networks), then both in.rdisc and in.routed are started.
