我有一个物理接口eth0,我想创建两个虚拟接口并用eth0桥接它们.为此我做：
#Create the virtual interfaces tunctl -t tap0 tunctl -t tap1 ifconfig tap0 up ifconfig tap1 up #Create the bridge brctl addbr br0 brctl stp br0 off brctl addif br0 eth0 brctl addif br0 tap0 brctl addif br0 tap1 #Turning up the bridge ifconfig br0 up
但是我的问题是,如果tap接口总是在桥中出现禁用,并且没有流量流向它们.
$brctl show br0
bridge name bridge id STP enabled interfaces
br0 8000.080027cabeba no eth2
tap0
tap1
$brctl showstp br0

有没有办法将tap接口设置为转发状态？我不明白为什么他们不是因为STP被禁用.

解决方法
当用户打开设备手柄时,仅在点击时设置载波(IFF_RUNNING).
对于使用tunctl创建的持久性点击,您需要一个附加到点击的应用程序,例如：
