command script for network
netstart is the command script that is
invoked by rc(8) during an automatic reboot and after single-user mode is
exited; it performs network initialization.
netstart script can also be used to
start newly created bridges or interfaces, or reset existing interfaces to
their default state. The behaviour of this script is (or can be) controlled
to some extent by variables defined in
rc.conf(8), which specifies which daemons and services are to be
During the system boot,
netstart performs the following
operations, in the sequence given:
- Set the machine's name.
- Configure the loopback interface.
- Configure all the physical interfaces.
- Configure the following non-physical interfaces: trunk(4), vlan(4), pfsync(4), and carp(4).
- Initialize the routing table and set up the default routes.
- Configure the remaining non-physical interfaces: pppoe(4), gif(4), and gre(4).
- Configure all bridge(4) interfaces.
After the system is completely initialized, it is possible to start a newly created interface or bridge(4), or reset an existing interface to its default state, by invoking the following, where foo0 is the interface or bridge name:
To enable multicast(4) routing, the net.inet.ip.mforwarding and/or net.inet6.ip6.mforwarding sysctl(8) variables should be set to 1. Multicast routing is only enabled if multicast is set to "YES" in rc.conf.local(8). Other cases are configuration errors and will cause multicast routing not to be enabled.
