48 Instead, it is included by the
49 various generic startup scripts in

52 internal actions according to the settings found there.
56 file is included from the file

58 which specifies the default settings for all the available options.
59 Options need only be specified in

1055 One can configure more than one IPv4 address with the
1056 .Va ipv4_addrs_ Ns Aq Ar interface
1058 One or more IP addresses must be provided in Classless Inter-Domain
1059 Routing (CIDR) address notation, whose last byte can be a range like
1061 In this case the address 192.168.0.5 will be configured with the
1062 netmask /24 and the addresses 192.168.0.6 to 192.168.0.23 with
1063 the non-conflicting netmask /32 as explained in the

1068 an example could look like:
1070 ipv4_addrs_ed0="192.168.0.1/24 192.168.1.1-5/28"
1073 It is also possible to add IP alias entries using
1076 Assuming that the interface in question was
1079 something like this:
1081 ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
1082 ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"

1097 ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"
1100 Then note that alias4 would
1102 be added since the search would

1133 It is possible to bring up an interface with DHCP by adding
1136 .Va ifconfig_ Ns Aq Ar interface
1138 For instance, to initialize the

1146 Also, if your interface needs WPA authentication, it is possible to add
1149 .Va ifconfig_ Ns Aq Ar interface
1152 Finally, you can add
1154 options in this variable, in addition to the
1155 .Pa /etc/start_if. Ns Aq Ar interface
1157 For instance, to initialize the
1159 device via DHCP, using WPA authentication and 802.11b mode, it is
1160 possible to use something like:
1162 ifconfig_wi0="DHCP WPA mode 11b"

1167 form, a fallback variable
1168 .Va ifconfig_DEFAULT
1170 It will be used for all interfaces with no
1171 .Va ifconfig_ Ns Aq Ar interface
1173 This is intended to replace the no longer supported
1177 It is also possible to rename interface by doing:

1180 ifconfig_net0="inet 10.0.0.1 netmask 0xffff0000"
1182 .It Va ipv6_network_interfaces
1184 This is the IPv6 equivalent of
1185 .Va network_interfaces .
1186 Instead of setting the ifconfig variables as
1187 .Va ifconfig_ Ns Aq Ar interface
1188 they should be set as
1189 .Va ipv6_ifconfig_ Ns Aq Ar interface .
1190 Aliases should be set as
1191 .Va ipv6_ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n .
1192 .Va ipv6_prefix_ Ns Aq Ar interface
1194 Interfaces that do not have a
1195 .Va ipv6_ifconfig_ Ns Aq Ar interface
1196 setting will be auto configured by
