.SH DESCRIPTION
.LP
The \fBrouteadm\fR command is used to administer system-wide configuration for
IP forwarding and routing. IP forwarding is the passing of IP packets from one
network to another; IP routing is the use of a routing protocol to determine
routes.
.sp
.LP
IP forwarding and routing functions are also represented as services within the
service management facility (SMF), and can be administered by means of
\fBsvcadm\fR(8) also, using the following fault management resource
identifiers (FMRIs):
.sp
.in +2
.nf
svc:/network/ipv4-forwarding:default
svc:/network/ipv6-forwarding:default
svc:/network/routing/route:default
svc:/network/routing/ripng:default
.fi
.in -2

.sp
.LP
See EXAMPLES for relevant examples.
.sp
.LP
In addition to enabling and disabling routing and forwarding, \fBrouteadm\fR is
used to interact with SMF-based routing daemon services. Routing daemon
services are identified by the presence of a \fBrouteadm\fR application
property group, which \fBrouteadm\fR uses in administering the given service.
Routing daemon services can also specify properties relating to their operation
in the \fBrouting\fR application property group; these can be modified by means
of routeadm -m. If an FMRI for a service without such a property group is
specified, an error is issued and the operation is not carried out. If a
routing daemon has not been converted to SMF, the \fBipv4\fI[or
6]\fR-routing-daemon\fR, \fBipv4\fI[or 6]\fR-routing-daemon-args\fR, and
\fBipv4\fI[or 6]\fR-routing-stop-cmd\fR variables can be used to specify the
appropriate daemon for IPv4 or IPv6 routing. \fBrouteadm\fR will then run that
daemon using the \fBsvc:/network/routing/legacy-routing:ipv4\fR\fI[or 6]\fR
service as appropriate. This conversion process occurs when you issue an enable
(\fB-e\fR), disable (\fB-d\fR) or an update (\fB-u\fR) command.

.RS 2
The root file system of any non-global zones must not be referenced with the

compromise the security of the global zone, and might damage the non-global
zone's file system. See \fBzones\fR(7).

Apply the currently configured options to the running system. These options

of daemon stop commands, which might include a set of arguments, to a simple
enabling of the appropriate service.

.RE

.sp
.LP
The forwarding and routing settings are related but not mutually dependent. For
example, a router typically forwards IP packets and uses a routing protocol,
but nothing would prevent an administrator from configuring a router that
forwards packets and does not use a routing protocol. In that case, the
administrator would enable forwarding, disable routing, and populate the
router's routing table with static routes.
.sp
.LP
The forwarding settings are global settings. Each interface also has an
\fBIFF_ROUTER\fR forwarding flag that determines whether packets can be
forwarded to or from a particular interface. That flag can be independently
controlled by means of \fBifconfig\fR(8)'s router option. When the global
forwarding setting is changed (that is, \fB-u\fR is issued to change the value
from \fBenabled\fR to \fBdisabled\fR or vice-versa), all interface flags in the
system are changed simultaneously to reflect the new global policy. Interfaces
configured by means of DHCP automatically have their interface-specific
\fBIFF_ROUTER\fR flag cleared.
.sp
.LP
When a new interface is plumbed by means of \fBifconfig\fR, the value of the
interface-specific forwarding flag is set according to the current global
forwarding value. Thus, the forwarding value forms the "default" for all new
interfaces.
.SH EXAMPLES
.LP
\fBExample 1 \fREnabling IPv4 Forwarding
.sp
.LP
IPv4 forwarding is disabled by default. The following command enables IPv4
forwarding:

.sp
.in +2
.nf
example# \fBrouteadm -e ipv4-forwarding\fR
.fi
.in -2
.sp

.LP
\fBExample 2 \fRApply Configured Settings to the Running System
.sp
.LP
In the previous example, a system setting was changed, but will not take effect
until the next reboot unless a command such as the following is used:

.sp
.in +2
.nf
example# \fBrouteadm -u\fR
.fi
.in -2
.sp

.sp
.LP
An alternative to the above two steps is to simply enable the equivalent SMF
service:

.sp
.in +2
.nf
