I think he's saying that NetBSD is behaving as a layer 2 switch with 2
links. Spanning tree "solves" which interface is active elsewhere (or
can NetBSD run it? I don't know). Since you have a switch, frames are
sent to whatever interface owns the IP via the arp table. So it only
takes 1 of the 2 links to be up, doesn't matter which.

So it's not load balancing, but I think that was the point of the
original post. And I'm confused about "link1" in agr as well now that
I read it again.
