That happens all the time, we're running a lot of multi-radio nodes.

I most respectfully disagree.

In this case, Babel is simply unable to provide the information you want.
Babel only knows about neighbouring *interfaces*, it doesn't know whether
the neighbouring interfaces belong to the same node or not.

I'll repeat this, because it's important.  If a Babel node sees two
neighbouring interfaces A and B, it cannot tell if A and B belong to the
same node or not.
