网桥配置

配置原文

# In case of atheros and nl80211 driver interfaces, an additional
# configuration parameter, bridge, may be used to notify hostapd if the
# interface is included in a bridge. This parameter is not used with Host AP
# driver. If the bridge parameter is not set, the drivers will automatically
# figure out the bridge interface (assuming sysfs is enabled and mounted to
# /sys) and this parameter may not be needed.
#
# For nl80211, this parameter can be used to request the AP interface to be
# added to the bridge automatically (brctl may refuse to do this before hostapd
# has been started to change the interface mode). If needed, the bridge
# interface is also created.
#bridge=br0

• linux_ioctl.c 包含网桥相关操作，后续是否会升级为 netlink

OpenWRT 默认配置

bridge=br-lan

• OpenWRT 作为路由器，AP 通常加入 lan 网桥

OpenWRT 配置脚本

待确认

OpenWRT uci 配置

config wifi-iface 'wifinet0'
    option device 'radio1'
    option mode 'ap'
    option ssid 'OpenWrt'
    option encryption 'none'
    option network 'lan'

• 此处的 lan 即为 br-lan，OpenWRT 的网络接口概念建议阅读 netifd 的设计思想

OpenWRT uci 配置命令

uci set wireless.wifinet0.network='lan'

VLAN 配置
