.TH DEFAULTROUTER 4 "Aug 17, 2004"
.SH NAME
defaultrouter \- configuration file for default router(s)
.SH SYNOPSIS
.LP
.nf
\fB/etc/defaultrouter\fR
.fi

.SH DESCRIPTION
.sp
.LP
The \fB/etc/defaultrouter\fR file specifies a IPv4 host's default router(s).
.sp
.LP
The format of the file is as follows:
.sp
.in +2
.nf
IP_address
\&...
.fi
.in -2
.sp

.sp
.LP
The \fB/etc/defaultrouter\fR file can contain the IP addresses or hostnames of
one or more default routers, with each entry on its own line. If you use
hostnames, each hostname must also be listed in the local \fB/etc/hosts\fR
file, because no name services are running at the time that \fBdefaultrouter\fR
is read.
.sp
.LP
Lines beginning with the ``#'' character are treated as comments.
.sp
.LP
The default routes listed in this file replace those added by the kernel during
diskless booting. An empty \fB/etc/defaultrouter\fR file will cause the default
route added by the kernel to be deleted.
.sp
.LP
Use of a default route, whether received from a \fBDHCP\fR server or from
\fB/etc/defaultrouter\fR, prevents a machine from acting as an IPv4 router. You
can use \fBrouteadm\fR(1M) to override this behavior.
