当我编译完内核参数后，

# /sbin/sysctl -p

error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key
error: "net.bridge.bridge-nf-call-iptables" is an unknown key
error: "net.bridge.bridge-nf-call-arptables" is an unknown key

去网上一查，发现缺少bridge这个模块文件

通过执行 ：

  modprobe bridge

再一次：

# /sbin/sysctl -p

net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0
