Hi,all.
I'm running zebra-0.92a on linux kernel-2.4.18. I have a question about kernel-routing process interface.
When I configure, I can select NETLINK or IOCTL as kernel-routing process interface. I think IOCTL carries information in only process->kernel direction, not in kernel->process direction.
I have a question.
I think when I can select IOCTL as kernel-process interface, it have differences about information between kernel and routing process. For example, when I change interface status by "ifconfig" command, The information in kernel is updated. But in routing process not updated. (because IOCTL is process->kernel direction interface)
Is it no matter about such a specification?
Is IOCTL already obsolete ? The time when kernel didn't have NETLINK method, Would something bad happen?
