The draft says:

   Component links may be unnumbered, or the various component links
   may be numbered differently, or all components links may be
   numbered identically.  In the first two cases, the bundled link
   is unnumbered by default;

So, if the *components* are numbered differently, the *bundle* is
unnumbered.  This can of course be overridden by configuration.

Component addresses will not be advertised for *TE* -- that's what
the bundle is for.

How could this situation occur?  Perhaps it is desired for IP
forwarding and regular SPF that each component link is numbered
differently from other components; but for TE, a single bundle
is desired to reduce link state.

I tried :-)  Let me know if it helped ....
