hmm, not sure I understand the question. Which "area 0 solution" are you
referring to here? Putting the backdoor link into area 0? Not sure if
this works. If you turn your CE into an ABR, I think it will reject the
type 3's received by the PE (via the non-zero area on the PE-CE link),
including the ones from other, remote CE sites..
please elaborate and describe the overall topology..
