Two interfaces on the same subnet is not supported without IPMP.

So far, so good, right? Now here's the perplexing bit: despite both
interfaces seeming to be bound to the right IP address, I can only
connect to or ping the machine if hme0 is plugged in. rge0's link
light is lit, as is the corresponding LED on the switch. I've also
tried different cables and a different switch port, all to no avail.

I'll bet the machine is pinging rge0 just fine, but all replys to the
ping are going back via hme0.

Snoop -d rge0 on the box should show the incoming packets, but not the
outbound replies.

If you 'ifconfig down' the hme0, I would think the pings would start
working.
