  • ndc命令
    ``` 创建网络 ndc network create 999

将接口添加到网络 ndc network interface add 999 usb0

做了上面两个动作后, 就可以在策略表里看到关于usb0的策略了 ip -6 rule
0: from all lookup local 10000: from all fwmark 0xc0000/0xd0000 lookup legacy_system 11000: from all iif lo oif dummy0 uidrange 0-0 lookup dummy0 11000: from all iif lo oif usb0 uidrange 0-0 lookup usb0 16000: from all fwmark 0x10063/0x1ffff iif lo lookup local_network 16000: from all fwmark 0x103e7/0x1ffff iif lo lookup usb0 17000: from all iif lo oif dummy0 lookup dummy0 17000: from all iif lo oif usb0 lookup usb0 18000: from all fwmark 0x0/0x10000 lookup legacy_system 19000: from all fwmark 0x0/0x10000 lookup legacy_network 20000: from all fwmark 0x0/0x10000 lookup local_network 23000: from all fwmark 0x3e7/0x1ffff iif lo lookup usb0 32000: from all unreachable
