Mike,

I think you're making the assumption that no ELAN is bigger than
a peer group.  That may often be true but it certainly is possible
to have them bigger than that (especially if you have special
reasons for having particularly small peer groups).  If you have
a multi-PG ELAN, you would also want advertisement of the LECS for
that ELAN over the entire set of PGs it occupies.
