Hi Vivien Chappelier, In my use case, a security appliance provides security to 100 networks and a user space process which receives control traffic from these 100 networks. Earlier we were using VRF ID patch , so my objective of having separate routing table for each network was achieved. Now I have to customize 2.6.27 kernel to achieve the above requirement. I have compiled the 2.6.27 kernel with CONFIG_NAMESPACES=y # CONFIG_UTS_NS is not set # CONFIG_IPC_NS is not set # CONFIG_USER_NS is not set # CONFIG_PID_NS is not set CONFIG_NET_NS=y CONFIG_SYSFS=y CONFIG_MACVLAN=y CONFIG_VETH=y Please clarify me 1)Will these 6 patches satisfy my requirement ? Do I need any additional patches other than the 6 patches? 2)Please let me know the recommended iproute2 version . 3)Network Namespace object ID starts from 1 ... 4095. Is my understanding correct ? 4)Are there any test programs to verify ?If so what is the recommended glibc version to compile these test programs? I will post my comments after testing this patch.
