I'm looking into some network "weirdness", and I noticed that a CentOS 6 system with multiple IP addresses (load balancer running keepalived) is sending ARP requests from apparently random source IPs. I would have thought that ARP requests would always come from the interface's "primary" IP (especially since keepalived adds all the virtual IPs with a /32 mask). This is probably not related to my problem, but I just thought it was odd. Is there a way to control this? -- Chris Adams <linux at cmadams.net>
