643 interpreter before configuring the interface as specified in the
644 .Va ifconfig_ Ns Aq Ar interface
646 .Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
649 It is possible to bring up an interface with DHCP by adding
652 .Va ifconfig_ Ns Aq Ar interface
654 For instance, to initialize the
656 device via DHCP, it is possible to use something like:
662 .Va vlans_ Ns Aq Ar interface
666 interface will be created for each item in the list with the
670 If a vlan interface's name is a number,
671 then that number is used as the vlan tag and the new vlan interface is
673 .Ar interface . Ns Ar tag .
675 the vlan tag must be specified via a
678 .Va create_args_ Ns Aq Ar interface
681 To create a vlan device named
685 with the vlan tag 101 and the optional the IPv4 address 192.0.2.1/24:
688 ifconfig_em0_101="inet 192.0.2.1/24"
691 To create a vlan device named
695 with the vlan tag 102:

718 devices must be created for each wireless devices as of
724 may be specified with an
725 .Va wlandebug_ Ns Aq Ar interface
727 The contents of this variable will be passed directly to

733 .Va ifconfig_ Ns Aq Ar interface
736 .Xr wpa_supplicant 8 .
738 .Xr wpa_supplicant.conf 5
739 for configuring authentication information.
743 options in this variable, in addition to the
744 .Pa /etc/start_if. Ns Aq Ar interface
746 For instance, to initialize the
748 device via DHCP, using WPA authentication and 802.11b mode, it is
749 possible to use something like:
752 ifconfig_wlan0="up DHCP WPA mode 11b"
754 .It Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
756 Configuration to establish an additional network address for

763 ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"
768 .Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
769 entry that is found, its contents are passed to
771 Execution stops at the first unsuccessful access, so if
772 something like this is present:

777 ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"
780 Then note that alias4 would
782 be added since the search would stop with the missing alias3 entry.
783 .It Va ifconfig_ Ns Ao Ar interface Ac Ns Va _name
787 It is possible to rename interface by doing:
789 ifconfig_ed0_name="net0"

792 .It Va network_interfaces
794 The list of network interfaces to configure on this host,
797 to configure all network interfaces
800 For example, if the only network devices to be configured are the loopback device
804 driver, this could be set to
807 .Va ifconfig_ Ns Aq Ar interface
808 variable is assumed to exist for each value of
810 .It Va ipv6_network_interfaces
812 This is the IPv6 equivalent of
813 .Va network_interfaces .
814 Instead of setting the ifconfig variables as
815 .Va ifconfig_ Ns Aq Ar interface
816 they should be set as
817 .Va ipv6_ifconfig_ Ns Aq Ar interface .
818 Aliases should be set as
819 .Va ipv6_ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n .
820 Interfaces that do not have a
821 .Va ipv6_ifconfig_ Ns Aq Ar interface
822 setting will be auto configured by
825 .Va ipv6_gateway_enable
828 Note that the IPv6 networking code does not support the
829 .Pa /etc/start_if. Ns Aq Ar interface
831 .It Va ipv6_prefix_ Ns Aq Ar interface
835 prefixlen 64 is used.
836 .It Va ipv6_default_interface
840 this is the default output interface for scoped addresses.
841 Now this works only for IPv6 link local multicast addresses.
842 .It Va cloned_interfaces
844 Set to the list of clonable network interfaces to create on this host.
846 .Va cloned_interfaces
847 are automatically appended to
