We do have accept data configured. I have to admit that even after reading the docs just now, I'm not really sure I understand what it's doing. It is standard in our templates, though, so every interface running VRRP has accept data configured. Passive learning is an interesting thought, but I'd still like to find the root cause of the problem: why don't the IP addresses respond to ARP requests from only this router? I'm nearly certain it's a server issue but I haven't encountered anything quite like this before. Thanks!
