| |
Hi,
Does someone know if there is some work in the area of NIC dual homing ? By NIC dual homing, I mean two network devices (e.g. Ethernet) that are connected to the same IP subnet but only one is active (at IP level) at a time. When a faulty condition is detected (e.g. link down or lack of I/O), the kernel switches to the second NIC. Such a similar feature exists in Tru64 UNIX (NetRAIN), HP-UX (APA) and Solaris (Sun Cluster pnmd). What is the best way to handle that in Linux ? I thought about an IP virtual device that could be mapped on two eternet NIC and some ioctl to switch from one NIC to another or a generic virtual ethernet driver that could handle two real ethernet drivers ?
Laurent
