我正在尝试使用vconfig在无线IPTV机顶盒（机顶盒）上的2个embedded式Linux SOC之间build立一个vlan。 SOC之间的物理连接是Marvell 88E60xx交换机。 问题是，vlan需要是私有的。 如果有一个以上的IPTV STB，RPC（远程过程调用）从错误的STB获得响应，并且我使用的静态IP地址在networking上被复制。 我在Wireshark上看到这个。
为1.1.1.1（28：c8：7a：b5：ad：50）检测到的重复IP地址 – 也被28：c8：7a：b5：ad：10使用（第171帧）
我怀疑我缺less1或2个configuration步骤，但这是我第一次尝试build立一个VLAN。 这就是我如何在控制WiFi的SOC上configurationvlan
vconfig add br0 12 ip link set br0.12 up ifconfig br0.12 1.1.1.2 netmask 255.255.255.248 这就是我如何在控制IPTV的SOC上configurationvlan
ifconfig eth0 0.0.0.0 multicast up vconfig add eth0 0 ifconfig eth0.0 0.0.0.0 multicast up brctl addbr br0 brctl addif br0 eth0.0 brctl addbr br6 brctl stp br6 0 # spanning tree protocol off brctl setfd br6 0 # set bridge forward delay to 0 seconds vconfig add eth0 12 ifconfig eth0.12 0.0.0.0 multicast up brctl addif br6 eth0.12 ifconfig br6 1.1.1.1 up
这是控制WiFi的SOC的ifconfig

我能够通过closures这样的arp来隔离vlan
ifconfig br6 -arp #turn off arp
并像这样设置arp
arp -s 1.1.1.2 $WMAC
并在桥的另一边做类似的事情
ifconfig br0 -arp #turn off arp ifconfig br0.12 -arp #turn off arp
和
arp -s 1.1.1.1 $EMAC
