在trunk文件夹下运行

mkdir -p files/etc/config

然后在 config 文件夹下新建network文件写入例如以下内容

config interface 'loopback'	option ifname 'lo'	option proto 'static'	option ipaddr '127.0.0.1'	option netmask '255.0.0.0'config globals 'globals'	option ula_prefix 'fd3b:272f:a046::/48'config interface 'lan'	option ifname 'eth0.1'	option force_link '1'	option macaddr '7a:20:00:02:5f:74'	option type 'bridge'	option proto 'static'	option ipaddr '192.168.20.1'	option netmask '255.255.255.0'	option ip6assign '60'config interface 'wan'	option ifname 'eth0.2'	option force_link '1'	option macaddr '7a:20:00:02:5f:75'	option proto 'dhcp'config interface 'wan6'	option ifname 'eth0.2'	option proto 'dhcpv6'config interface 'ppp0'	option ifname 'ppp0'	option service 'evdo'	option username 'card'	option password 'card'	option device '/dev/ttyUSB0'	option proto '3g'	option dialnumber '#777'	option apn 'ctnet'	option ipv6 'auto'config switch	option name 'rt305x'	option reset '1'	option enable_vlan '1'config switch_vlan	option device 'rt305x'	option vlan '1'	option ports '0 1 2 3 6t'config switch_vlan	option device 'rt305x'	option vlan '2'	option ports '4 6t'

network 内容可依据需求更改内容。

原理是  make 后 files/etc/config/network 会覆盖开发板的 network 文件
