Average number of tunnel keep-alives on exit link is 4. For MANETs with few exit links, this models doesn't work well. But this becomes less common, I think.

Not sure I get how this works.

Okay, maybe "HNA with low metric". So that these "external prefixes
behind the tunnel" have a well defined cost from the mesh point of
view.
