在linux网桥中始终禁用tap接口

概述我有一个物理接口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 interfacestunctl -t tap0tunctl -t tap1ifconfig tap0 upifconfig tap1 up#Create the bridgebrctl addbr br0brctl stp br0 offbrctl addif 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 interfacestunctl -t tap0tunctl -t tap1ifconfig tap0 upifconfig tap1 up#Create the brIDgebrctl addbr br0brctl stp br0 offbrctl addif br0 eth0brctl addif br0 tap0brctl addif br0 tap1#Turning up the brIDgeifconfig 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.

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：
